Virtues of al-Hasan bin Ali (may Allah be pleased with him): the pledge of allegiance to al-Hasan in Kufah

It is narrated from Sayyidah Umm Bakr bint al-Miswar (may Allah be pleased with her) that Sayyiduna Hasan bin Ali (may Allah be pleased with them both) was poisoned several times, and each time he survived its effect, until the last time he was poisoned, in which he died; from the severity of that poison his liver would come out in pieces. When he died, the women of Banu Hashim mourned for him for a month.

Ibn Umar (al-Waqidi) said: Hafs bin Umar narrated to us from Abu Ja'far that the people kept weeping over (the death of) Sayyiduna Hasan bin Ali (may Allah be pleased with them both) (from intense grief), and during that time even the markets stayed closed (the business of life came to a halt).

Ibn Umar (al-Waqidi) said: Ubaydah bint Nabil narrated to us from Sayyidah Aishah bint Sa'd (may Allah be pleased with her) that the wives of Sayyiduna Hasan bin Ali (may Allah be pleased with them both) observed mourning for one year.

Ibn Umar (al-Waqidi) said: Dawud bin Sinan told us: I heard Tha'labah bin Abi Malik say: We were present on the day Sayyiduna Hasan bin Ali (may Allah be pleased with them both) died, and we buried him in Jannat al-Baqi'. So many people had gathered there at that time that if even a needle had been dropped, it would have fallen on someone's head rather than on the ground.

Ibn Umar (al-Waqidi) said: Ali bin Muhammad told me that Maslamah bin Muharib said: Sayyiduna Hasan bin Ali (may Allah be pleased with them both) died in the year 50 AH, on 5 Rabi' al-Awwal, at the age of 46. Sa'id bin al-As led his funeral prayer, and he was weeping; and his illness lasted forty days.

Abu Ishaq said: Allegiance was given to Abu Muhammad Sayyiduna Hasan bin Ali bin Abi Talib (may Allah be pleased with them both) in Kufah immediately after the martyrdom of the Commander of the Believers (Sayyiduna Ali, may Allah be pleased with him), and he took the pledge of allegiance from his companions. Then Harithah bin Mudarrib narrated to me; he said: I heard Sayyiduna Hasan bin Ali (may Allah be pleased with them both) say: "By Allah, I will take your pledge only on the condition I tell you." They asked: What is that condition? He said: "You will make peace with whomever I make peace with and fight whomever I fight." Then when the pledge was complete, he addressed the people.
