The hours of fasting in Ramadan vary based on the geographical position of the city where one lives. In some regions, the fasting hours might be extremely long while in other places it might be too short such that one wonders if the goal of fasting (Sawm) has been accomplished or not. Extended fasting might cause difficulties.

Some might complain that there is no advantage in fasting long days. Others might find excuses to avoid fasting altogether. But, Islam does not want Muslims to suffer. There are, therefore, some rulings on how to fast on very long days and very short days, that we review them all next.

Fasting in Ramadan on Extremely Short Days

In the case where the days are very short, one should perform fasting in its typical way, from dawn to sunset, according to the prayer times. Hence, short fasting hours does not change the default time rulings on fasting (Swam) [1].   

Fasting Is Not to Suffer

Fasting is not a mere act of depriving oneself of foods or drinks, but it aims at spiritual growth and salvation, inner peace, exercising patience, strengthening the social ties and experiencing how poor people live their lives [2].

Hence, the obligation on fasting is not to make people suffer; as it is stated in Surah Baqarah: “Allah intends for you ease and does not intend for you hardship” (2:185). So, there are some rulings on long fasts which make them less difficult.

Fasting in Ramadan on Very Long Days

Long fast (Swam), especially in hot summer days, is tough. In this case, one should fast according to the prayer times of his\her city of residence. But, if it is extremely difficult, whenever during the day he\she feels unable to continue, he\she is allowed to break the fast (Swam) and have to fast (it is obligatory, Wajib) later on for those missing (Qaza) fasts in shorter days of the current year and before the next Ramadan [1]

However, different religious experts (Mujtahids)  have different opinions on this matter. We explained one of those views above. There are two other opinions as follows and one of them might be the opinion of your religious expert (Mujtahid):

 In any case, one should fast according to the prayer times of the city of residence;
One should fast according to the prayer times in a “moderate region,” with the normal day length, that is on the same meridian as his\her city of residence.

Conclusion

Fasting is obligatory due to its spiritual and physical benefits. It is not to put pressure and make people suffer. If it is tough to fast in very long days, one can fast according to the rulings stated above.

The concept of responsibility in Islam includes a wide range of matters. Human beings have certain responsibilities in Islam toward others and themselves. All creatures in this universe are naturally inclined to move toward the perfection considered for each of them. They are created in the most proper form, then, have been provided with the conditions and requirements that God has planned (20:50).

Nonetheless, none of them knows neither the path that they should pave nor the final target; except humans. According to the Quran, human beings are created for specific reasons (23:115), and they have duties and responsibilities (75:36). The most prominent responsibility in Islam that one has is towards God, as explained in the first part of the article. He\she is also responsible towards him\herself. This category of duties is discussed here.

The Rights that One Has Over Him\herself as His/her Responsibility in Islam

According to Imam Sajjad (AS), the duties of every human being towards him\herself are to serve only God by all his\her capabilities and every part of the body; and, to respect the rights of each part of the body [1]. Hence, the responsibilities in Islam of every human being towards him\herself can be divided into spiritual and physical items.

Responsibility in Islam towards the Soul

According to the Quran, God breathed into the human being of His [created] soul after he was proportioned (38:72). This makes the human’s soul of great value in Islam. Accordingly, every individual has certain responsibilities towards his\her valuable soul. These duties can be summarized in one sentence: to utilize the soul in the way of God.

That is to apply all spiritual capacities in the obedience to God and to do what brings bout God’s satisfaction. This requires one to keep the soul alive and pure by practicing what is ordered to or invited to in Islamic teachings like prayer (Salat), fasting (Sawm), pilgrimage (Hajj), etc., also by preventing any harm to the soul such as anxiety, depression, etc. 

The Rights that the Parts of the Body Have and One's Responsibility in Islam toward them

One’s acts and words form and determine the his\her path in life. He\she does various acts (including good deeds, what is obligatory (Wajib) or recommended (Mustahab)) with different parts of the body and verbally thank God (in the form of prayer) with the help of tongue and mouth. Hence, whatever one does concerning the obedience of God depends also on the parts of the his\her body. Therefore, he\she has some responsibilities towards them.

The Rights of the Tongue

Of the rights of the tongue are to [1]:

Avoid foul language and the sins that one might commit with the tongue, such as backbiting (ghibah) and slander. Prophet Muhammad (PBUH) said that: “Do not insult others, this turns them into your enemies” [2], and: “Whoever divulges the flaws and faults of another Muslim, God will reveal his flaws” [3]; 
Accustom it to saying pleasant beneficial words;
Force it to talk nicely and politely (2:83);
Stop it from talking too much and stay silent unless talking is beneficial; “Silence is a door to wisdom, it brings affection and guides to every blessing.” [4], and: "whoever believes in God and the Hereafter should say beneficial words, otherwise stays silent.” [5];
Think about what you are going to say and judge the words before you start talking because a wise person will be judged by his words; “A faithful person … thinks about his words first, and then says those words” [6].

The Rights of the Ears

The ears are like the doors to the heart; they transfer every word with either a positive or negative influence on the heart [1]. Imam Ali (AS) has prevented us from listening to the words without any advantage and benefit as they darken the heart and cause us to be blamed [7]. For example, whoever listens to backbiting is a partner of the backbiter [8]. Hence, one should control the ears to hear only nice and useful words that purify the heart or encourage good behavior [1].
