Abu Dawud Book 1, Hadith Number 180.
Chapter : Ablution does not become void by kissing a woman.
Narated By N/A : This tradition has been transmitted through another chain of narrators on the authority of ‘Aisha.
Abu Dawud said: Yahya b. Sa’id al-Qittan said to a person: Narrate these two traditions 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 a 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 narrate any tradition on the authority of ‘Urwah b. al-Zubair.
Abu Dawud said: Hamzah at-Zayyat reported a sound tradition on the authority of Habib. from ‘Urwah b. al-Zubair ‘from ‘Aisha.
