On this day, the fifteenth of the month of Ramadan, the believers, lovers of Ahl Al-Bayt (peace be upon them) celebrate the birth anniversary of the beloved grandson of the Messenger of Allah (Allah's prayers be upon him and upon his holy Household) Imam Al-Hassan Al-Mujtaba (peace be upon him), which was on the third year of Hijra, and other historians say it was on the second year.
The Imam is Al-Hassan son of Ali son of Abi Taleb son of Abd Al-Muttalib, the first grandson of the Messenger of Allah (Allah's prayers be upon him and upon his holy Household), he was called Abu Mohammad, and his titles were: As-Sayyed, Al-Sibt, Al-Ameen, Al-Hujjah, Al-Bar, Al-Naqi, AL-Zaki, Al-Mujtaba and Al-Zahid.
Imam Ali ibn Al-Hussayn (peace be upon both of them) said: When Fatima (peace be upon her) gave birth to Al-Hassan (peace be upon him), she said to Ali (peace be upon him): “Name him”, so he said: “I will not name him before the Messenger of Allah (Allah's prayers be upon him and upon his holy Household)”. So when he (Allah's prayers be upon him and upon his holy Household) came he said to Ali (peace be upon him): “did you name him?” He replied: “I would not name him before you”, so He said: “And I do not name him before my Lord, Mighty and Majestic”, So Allah revealed to Gabriel: “Mohammad has a son so descend and send him salams and congratulate him, and say to him: “Verily Ali is from you of the status which Haroun had from Musa, so name him after the son of Haroun.””, so Gabriel descended and congratulated the Prophet on behalf of Allah, then said: “Verily Allah orders you to name him after the son of Haroun. So the Prophet replied: “And what was his name?” He said: “Shabbar”. The Prophet said: “My tongue is Arab”. Gabriel said: “Name him Al-Hassan”, so he named him Al-Hassan."
Imam Al-Hassan (peace be upon him) was the best of the people of his time, the most ascetic and the master of worshippers. He used to perform pilgrimage on foot and maybe on barefoot. He used to cry when he remembers death, the Sirat and the Day of Resurrection. He was also known by his intelligence and wisdom since childhood. It is narrated that in his childhood, Imam Al-Hassan, who was seven years old, listened to the revelation in his grandfather’s meeting and memorized it. Then he came to his mother Fatima (peace be upon her) to recite it before her. When Imam Ali (peace be upon him) came to her, he found that she had known about the revelation that had at once been revealed to the Prophet (Allah's prayers be upon him and upon his holy Household). When he asked her about it, she replied that it was from her son Al-Hassan (peace be upon him).
Imam Al-Hassan (peace be upon him) was one of the most generous people, the kindest, and most charitable to the poor and the wretched. He did never reject a beggar at all. He was asked about that and he said, “I always beg Allah and look forward to His gift. Therefore, I feel shy to be a beggar and at the same time I reject a beggar. Allah has accustomed me to a habit that He pours on me His blessings and I have accustomed Him that I pour His blessings on people. I fear that if I stop my habit, He will stop His habit.’ Then he recited the following verses of poetry: “When an asker comes to me, I say: welcome to the One whose favour is urgently obligatory on me. And from His favour there is a favour on every favourer. And the best of one’s days is when he is asked (by a needy one)."
Needy people often crowded at the door of Imam Al-Hassan (peace be upon him) and he always gave them generously. One day, a nomad came to him asking for help. The imam asked his servant to give the nomad all that there was in the bursary. It was ten thousand dinars. The nomad said to the Imam Al-Hassan (peace be upon him), ‘Would you let me reveal my need and declare my praise?’ Imam Al-Hassan (peace be upon him) said to him, “We are people whose donation is fresh, in which hope and expectation revel. Our selves give before being asked, to save the face of one who asks. If the sea knows the abundance of our donation, it shall, because of shyness, flow over after its flooding.”
