Ja’far ibn Muhammad (AS) known as the Ja’far as-Sadiq (AS) is the sixth Shiite Imam. Imam Sadiq (AS) was born on 17 Rabi al-Avval 83th (702 CE) in Medina. His father, the previous Imam, was named Muhammad al-Baqir (AS) and his mother was called Umi-Farvah. After his father, Imam Sadiq (AS) became the Imam of the Shias and his leadership lasted for about 34 years. The era of Imam Sadiq (AS) was the time of instability and wars, since the Umayyad dynasty were weakened so much due to the battles they had in the Islamic territory. In addition , Abbasid dynasty were trying to topple the Umayyad government and reign over the whole Islamic world. The weakness of the rulers gave Imam Baqir (AS) and Imam Sadiq (AS) a perfect opportunity to spread the teachings of Shiism and train so many Shia scholars. At last, Imam Sadiq (AS) was martyred by the order of the Mansur (an Abbasid Caliph) on 148 H (765 CE). 

What does “Sadiq” mean?

The word “Sadiq” means an honest person who does not tell lies. 
Once, Imam Sajjad (AS), the grandfather of Imam Sadiq (AS) was asked: “Who is the Imam after you?”
“My son Muhammad (AS) who opens knowledge and after him his son Jafar who is called in the skies as ‘Sadiq’” Imam Sajjad (AS) replied. 
He was asked once more: “Why out of you all, he is called “Sadiq” while you all are honest?”
Imam Sajjad (AS) said: “Because the Prophet (PBUH & HP) said: ‘Name my son Jafar ibn Muhammd as “Sadiq” because there will be another Jafar in the future who falsely claims to be an Imam and he is named “liar” by Allah’” (On the contrary, Jafar ibn Muhammad is honest because he is a true Imam). (1)
The liar Jafar mentioned in the hadith is the son of Imam Hadi (AS), the eleventh Imam. 

The knowledge of Imam Sadiq (AS)

All Shiite Imams were known for their abundant knowledge in their time; but among all, Imam Baqir (AS) and Imam Sadiq (AS) were different. Due to the fact that Umayyad dynasty were weak and unstable in those times, Imam Baqir (AS) and Imam Sadiq (AS) had this chance to unveil the abundant knowledge of the Prophet’s household. 
About 4000 people learned from Imam Sadiq (AS) and narrated hadiths from him . (2)
Amr ibn Abi al-Mighdam, a Sunni scholar, says: 
“Every time I looked at the face of Jafar ibn Muhammad (AS), it would make me sure that he is a descendant of the prophets. Once, I saw him in Jamrah (a place in Mecca where the pilgrims gather) and he was telling people: ‘Ask me! Ask me!’” (3)
Hassan ibn Ali al-Vasha, a Shiite hadith narrator, says:
I saw about 900 sheikhs who all would narrate hadiths from Jafar ibn Muhammad (AS) (4).
Once Abu Hanifah, one of the most knowledgeable and popular Imams of the Sunnis, was asked: “Who do you think is the most knowledgeable person in religious fields?” he said: “I do not know anyone more knowledgeable than Jafar ibn Muhammad (AS)” (5).
Imam Sadiq (AS) is mostly known for his knowledge in Islamic laws and because of this, the Shiite school of law is called “Jafari School”. The hadiths narrated from Imam Baqir (AS) and Imam Sadiq (AS) are more than all the hadiths narrated from the Prophet (PBUH & HP) and the other Imams all combined together.

The moral attributes of Imam Sadiq (AS)

In addition to his wisdom and knowledge, Imam Sadiq (AS) was also known for his significant moral qualities. 
Muhammad ibn Talha says: 
“Imam Sadiq (AS) was the greatest person among the Prophet’s household and he was so knowledgeable and he would pray and recite the Quran so much and he was an ascetic person.” (6)
Malik ibn Anass, one of the Sunni school’s head, says: 
Every time I met him, he was in one of these three moods: either praying, fasting or whispering prayers (7).
Hisham ibn Salim, a famous apprentice of Imam Sadiq (AS) says:
Abu-Abdillah (Imam Sadiq (AS)) would always take a bag full of bread, meat and money in the darkness of the nights and go to the house of the needy ones in Medina and give it to them while they didn’t know him. Then, when he died, the people weren’t given those goods anymore and from that, they found out about his identity. (8)

If you feel you are not doing enough in your life and need to be a more productive Muslim, here we suggest some tips on planning a more productive lifestyle based on Islamic teachings. But before starting to review the tips on how to be a more productive Muslim, we should answer a "WHY" question? "Why do we want to or have to be more productive?" 

Merging into life routines can be hugely devastating for human beings. At the same time, many may not even recognize the fact that they are gradually being merged into their habits, and one day, they look back and look over their life, finding it all wasted. To avoid experiencing such hard and disappointing moments in life, Allah Almighty guides us through the Quran and the Islamic lifestyle provided in it. 

Islam's View on Life

Allah (SWT) introduces the ultimate goal of human creation as worshipping Him; "I did not create the jinn and the humans except that they may worship Me." (51: 56)

However, it is essential for human beings to understand the meaning of worshipping Allah (SWT). If, by glorifying Him, Allah (SWT) meant that people should spend all their time praying and fasting, then there was no need for all the other rulings and laws that the Quran describes regarding human beings' daily life including social, economic, political, etc. issues. 

The meaning of worshipping Allah (SWT) lies in the believers' understanding of the reason behind their behaviors and every single act and thought that they have; that is Allah Almighty's acceptance and satisfaction. It is crucial to keep in mind that worshipping Allah is not limited to praying and fasting, but every act of believers that is done in the way of gaining Allah's satisfaction is counted as worship.  That is why He recommends that all our deeds and actions should have a divine tint; "The coloring of Allah, and who colors better than Allah? And Him do we worship." (2: 138) 

Therefore, one can easily conclude that living an idle life is far from what Allah has expected from us. Allah (SWT) in the Quran encourages people not to waste even a single moment in their life when He says, "So when you are done, appoint, and supplicate your Lord." (94: 7 – 8)

The above verses show that for a more productive life, people should always have plans for their days, weeks, and years, so when they finish one task, they know what they should do next. Imam Musa al-Kazim (AS) says: "try that your daily time is divided into segments. One part for worshipping your Lord. One part for earning allowed (Halal) livelihood, a part for socializing with trustworthy friends, and another exclusively devoted to Lawful (Halal) pleasure with the family. [1]
We should still keep in mind that everything may not go exactly as we plan and not get disappointed if our plans do not go very well. Allah (SWT) says:

"Yet it may be that you dislike something, which is good for you, and it may be that you love something, which is bad for you, and Allah knows, and you do not know." (2: 216)

Therefore, keep a "to-do list" of your goals and plans for your years, months, weeks, and days. That will help you find less time in front of the TV, thinking that there is nothing else left to be done.

In the Quran, Allah counts some habits of those prosperous people. If we pay special attention to them, they help us have a more productive life. 

1- Those Who "Avoid vain talk" (23: 3) 

Vain talk does not necessarily apply to speaking to others. But any type of futile habit will take away one's prosperity, among which we can name unproductive use of social networks, useless friendships, ineffective discussions, etc.

 2- Those Who are Humble; "The servants of the All-beneficent are those who walk humbly on the earth" (25: 63)

Being humble and putting effort into reaching a humble character helps us be free from all useless social conflicts. Many people in human history wasted their lives looking abnormally beautiful or earning huge wealth. While the real prosperity belongs to those who beautify their soul, "Felicitous is he who purifies himself, celebrates the Name of his Lord, and prays. But you prefer the life of this world, while the Hereafter is better and more lasting." (87: 14- 17)

3- Those who ", and when the ignorant address them, they say, 'Peace!'" (25: 63)

Many people pay a lot of attention to their conversations with other people. So much that after each party or gathering, their mind is so busy analyzing what others told them and find out if they meant to humiliate or disrespect them. This habit takes a lot of energy from a person and prevents him/her from being a productive person. Therefore, Allah (SWT) suggests that if one wants to be a real servant of Him, he/ she should ignore all the things that may take away his concentration in serving Allah (SWT). 

4- Those who strive hard: "that nothing belongs to man except what he strives for" (53: 39)

There is nothing that people can not reach by their imagination and creativity. However, without effort and hard work, nothing is attainable. Through hard work, practice, and persistence human beings can gain what they plan for. Therefore, after planning for your life, and setting your goals that have a tint of God, you have to work hard and "… and once you are resolved, put your trust in Allah…" (3: 159) 

5. Eating and Sleeping Habits of a Productive Muslim

Allah also orders people to be careful about the health of their body and soul at the same time when He provides them with sleeping habits: "Stand vigil through the night, except for a little [of it], a half, or reduce a little from that, or add to it, and recite the Quran in a measured tone." (73: 2- 4) 

One may say that the above verses apply only to the Prophet (PBUH&HP), but whoever follows these habits will achieve high spiritual levels; "And keep vigil for a part of the night, as a supererogatory [devotion] for you. It may be that your Lord will raise you to a praiseworthy station." (17: 79) Studying the biography of great believers, one can realize that the night watch was one of the most explicit parts of their daily routine.

 Allah (SWT) also orders people to watch what they eat, as eating habits have a significant effect on the human body and soul: "Let man consider his food" (80: 24) Having a healthy body and soul will help people to be more productive. 

6. Reciting the Quran

One great habit that can help people have a more productive life, as recommended by Allah (SWT), is reciting the Quran: "…So recite as much of the Quran as is feasible. …" (73: 20)

Reading the Quran and contemplating over its stories, examples and even rulings can help us have a more creative and analytic mind, and this is aside from the miraculous impact that reciting the Quran has on human soul and body "We send down in the Quran that which is a cure and mercy for the faithful…" (17: 82) 

7. A Productive Muslim Takes Practical steps

In the Quran, Allah (SWT) has always put faith beside practice, which shows the importance of taking action instead of being passive human beings: "By time! Man is indeed in loss, except those who have faith and do righteous deeds, and enjoin one another to [follow] the truth, and enjoin one another to patience." (103: 1- 3) 

8. Remembering Death and Thinking of Hereafter

Imam Ali (AS), in his letter to his son, Imam Hasan (AS), says: "My son! Know that you were created for the Hereafter, not for this world, for extinction (in this world), not for permanence, and death, not for life. You are in an abode from which you must depart, in a place from which you acquire your provisions, and on a path to the Hereafter." [2]

It is vital to keep in mind that we are not going to live in this world forever. We are here for a short time, and we need to prepare for the real life as mentioned in the Quran: "The life of this world is nothing but diversion and play, but the abode of the Hereafter is indeed Life (itself), had they known!" (29:64). Therefore, if we live every moment of our life knowing that we are traveling to the real world any moment, then we will try our best to make the best out of our time, energy, and talents.

 In sum, having a more productive life is a necessity for all Muslims, and to improve one's productivity, planning a life based on the Quran and Islamic teachings can be a great guideline.
