Recitation of Hadith Al-Kisa by Syed Walid Mazeedi.
Hadith Al-Kisa (Narration of the Cloak) is the narration of an incident where the Prophet Mohammed (saw) gathered Ali, Hassan, Hussayn and Fatema (peace be upon them all) under his cloak and announced them as his Ahl (Family). It was then that the second part of verse 33:33 of the Holy Quran was revealed, known as "Ayat al-Tathir" (Verse of Purification), in which Allah states He has purified the Family of the Prophet (Ali, Hassan, Hussayn and Fatema), thus proving their infallibility.
This narration has been narrated by many people, including Umme Salma, Jabir ibn Abdullah Ansari, Ayesha, and Ibne Abbas. There are also various modifications and differences between the narrations of the different people. The most authentic version of Hadith Al-Kisa, according to the Shia, is that version which has been narrated by Jabir ibn Abdullah Ansari, all other versions have either been edited or are incomplete.
