Chapter 1: Purification (Kitab Al-Taharah)
Narrated Aisha, Ummul Mu' minin: The Prophet (ﷺ) kissed me and did not perform ablution. Abu Dawud said: This tradition is Mursal (i. e. where the link of the Companions is missing and the Successor reports from the Prophet directly). Ibrahim at-Taimi did not hear anything from 'Aishah. Abu Dawud said: Al-Firyabi and other narrated this tradition in a like manner.
