This tradition has been reported through another chain of narrators on the authority of 'Aishah. Abu Dawud said: Yahya b. Sa'id al-Qattan said to a person: Narrate these two tradition from me, that is to say, one tradition on the authority of al-A'mash from Habib (about kissing); another through the same chain about a woman who has prolonged flow of blood and she is asked to perform ablution for every prayer. Yahya said: Narrate from me that both these traditions are weak in respect of their chains. Abu Dawud said: Al-Thawri is reported to have said: Habib narrated this tradition to us only on the authority of 'Urwat al-Muzani, that is, he did not narrated any tradition on the authority of 'Urwah b. al-Zubair. Abu Dawud said: Hamzah al-Zayyat reported a sound tradition on the authority of Habib, from 'Urwah b. al-Zubair from 'Aishah.
