Hagar, who left behind a sainted child that later became the forefather of the Holy Prophet Muhammad (PBUH&HP), is the symbol of a devoted and obedient woman to God. Although her name is not directly mentioned in the Quran, in many Islamic quotes (hadiths) she is known as an example of faith in Allah that makes her a role model for every Muslim.

Ishmael (AS)’s Birth

Being barren, Sarah the prophet Abraham(AS)’s wife, told him to marry her housemaid, Hagar, as a second wife. After Hagar gave birth to a blessed child, Ishmael (AS), Allah ordered Abraham (AS) to emigrate from Egypt to Mecca with Hagar and infant Ishmael (AS).

With the guidance of Gabriel, they stopped to camp at a bleak, isolated place with a limited supply of food and water. That was the land on which the Kaaba was later built. Soon after this, Abraham (AS) received another command from Allah to leave his beloved wife and child behind in that harsh condition.

Abraham (AS) submitted to the command of Allah and patiently tolerated this separation while praying for them: “Our Lord! I have settled part of my descendants in a barren valley, by Your Sacred House, our Lord, that they may maintain the prayer. So make the hearts of a part of the people fond of them, and provide them with fruits, so that they may give thanks” (14:37).

Hagar's Faith Was Paid

At that time some people would come to Mecca to pray, but no one inhabited there because of the unbearable living conditions[1]. Believing in divine predestination and knowing that God had not forgotten them, Hagar endured the hard conditions until she ran out of food and water.

Seeing her child dying of thirst, she ran to the top of Mount Safa hoping to find some water, but she found nothing. So she continued her search and ran to Mount Marwa instead, again in the hope to find some water. She continued and ran seven times between these two mounts, Safa and Marwa, with faith in divine mercy.

She had such trust in her God that she did not give up searching for water even for a moment. Then, she noticed water bubbling up from somewhere under Ishmael (AS)’s feet. Hagar’s patience and sincere efforts were paid; they survived.

Later on, the place where the water came to the surface was named Zamzam Spring. This act of Hagar became a big sign (called sa’i) for billions of Muslims through the ages, especially during Hajj, reminding them of the pure struggles of a faithful woman and the subsequent Divine Favour [1]. Hagar showed a deep sincerity to God by attesting with certainty that Allah had not abandoned her and her child.

Second Divine Trial For Hagar

After Zamzam water sprang out from the Earth, a tribe who lived in the vicinity of Mecca realized and came to settle there. Abraham (AS)’s prayer was responded to; Hagar and her son were not alone anymore. He came to visit Hagar and Ishmael (AS) time by time. As he knew the capabilities and merits of Hagar, he entrusted the training and education of Ishmael (AS) to her mother.

Some years later when Ishmael (AS) became 13 [2], another divine test awaited him and his parents; Allah ordered Abraham (AS) to sacrifice Ishmael (AS): “When he was old enough to assist in his endeavor, he said," My son! I see in a dream that I am sacrificing you. See what you think." He said," Father! Do whatever you have been commanded. If Allah wishes, you will find me to be patient” (37:102).

The full story is mentioned in the chapter (Surah) Al-Saaffat (verses 102-111) in the Quran. Growing up with the religious teachings of her mother, Ishmael (AS) obeyed Allah’s will. But it was no more than a trial for both Ishmael (AS) and Abraham (AS) in which they succeeded: “This was indeed a manifest test, Then We ransomed him with a great sacrifice, and left for him a good name in posterity” (37: 106-108). 

Rested in Peace, Close to the Kaaba

Hagar was buried beside the Holy Kaaba after her demise. Her grave is located in Hijr Ishmael; a crescent-shaped area immediately adjacent to the Kaaba. Every Muslim who performs Hajj is obliged to circumambulate around it; the place where Abraham (AS) had constructed a shelter for Ishmael (AS) and Hagar[3] before he left them in that desert. This is how Allah rewards his sincere obedient believers.

Following the discussions on the concept of responsibility in Islam and Muslims' duties towards other human beings, this article reviews the duties towards the teachers, students, and young and older adults.

The Responsibility in Islam Towards Mentors

Teachers are acknowledged and valorized in Islam. It is said that God, angels, earth inhabitants and even the small ants in their nests and the fish in the seas, all salute the mentors who invite to goodness [1]. Imam Ali (AS) said that whoever has taught me a word has made me “his slave”[i] [2]. Regarding the Islamic resources, the rights of the mentor over the students are:

to be polite and grateful to the mentor, and honor him\her [3];
to sit down politely in his\her presence such that to face him\her directly [3];
to listen carefully to him\her and forget anything else during the session except what the mentor explains [3];
not to answer the questions that the mentor has been asked about and let him\her to reply [3];
to lower your voice when talking to him\her [3] as a means of showing the respect for him\her;
to ask in order to know and not to annoy the mentor or to mock him\her [4] and then to listen carefully to the answer of the question [5];
not to talk and whisper to anybody in his\her presence [3] otherwise the mentor feels being ignored;
not to talk behind other people’s back with him\her [3] since this is an unpleasant act which also bothers the audience ;
not to let others insult the mentor or lie about him\her [3];
not to reveal his\her deficiencies and to tell others about his\her positive characteristics [3].

The Rights of the Knowledge-seeker and The Responsibility in Islam Towards Them[ii]

Seeking knowledge is such important in Islam that according to Prophet Muhammad (PBUH&HP), trees, winds, clouds, seas and stars, plants and everything that the sunshine falls on, all ask for mercy for whoever seeks knowledge [6]. Also, the Prophet (PBUH&HP) said that whoever seeks knowledge is beloved by God, angels, and prophets and good for them on the judgment day [7]. Of the rights of the knowledge-seekers over their mentor are:

To be kind to them [8];
To be humble and flexible to them [8];
To know their names and some details about each of them [8]. This helps to maintain a better relationship and consequently to better teach and educate them;
To respect their character and to consider their words and thoughts [8];
To equally love them and pay attention to them [8]. In this regard, mentors are almost like judges in Islam;
To teach with serenity and dignity [8], therefore, his\her lessons impress their mind and soul  ;
To be tolerant of them and answer their questions properly [8];
To consider and support kindly the newcomers [8];
To honestly tell if he\she does not know the answer to a question [8] instead of saying what he\she is not sure about;

The Rights of Young People

Of the rights of young people over older adults and their responsibility in Islam are: 

To be kind to them [3];
To be engaged in their education and training [3];
To ignore and forgive their mistakes and hide their deficiencies [3];
To tolerate them, be patient with them and help them in difficulties [3];
If the young people do something wrong because they are naive, the older adults should not reveal that [3];
To avoid arguments and conflicts with them [3].

The Rights of Elderly people

The responsibility in Islam of the younger people toward the elderly include:

To respect them since they are older than you [3];
If they argue with you, do not react unpleasantly [3];
If you accompany each other on the way, do not overtake them [3];
If they do not know about something, do not humiliate them [3];
And, if they ignore you because you do not know something, keep calm and do not react as they are older than you [3].

Notes: 
[i] The word “slave” here does not mean servant, but is used to valorize the mentor and emphasizes the importance of respecting him\her.
[ii] Knowledge-seeker is used as a more general word than a student to cover whoever seeks knowledge.
