Chapter 1: The Book of Purification
It was narrated that 'Aishah said: "They say that the Prophet (ﷺ) made a will for 'Ali,[1] but he called for a basin in which to urinate, then he went flaccid suddenly (and died), so how could he leave a will?!"
The Shaikh said: Azhar (one of the narrators) is Ibn Sa' d As-Samman.
[1] Meaning, appointing him as the Khalifah.
