Sunan Abi Dawud Book 2, Hadith 319
The Prophet (ﷺ) was (once) praying. A kid went passing in front of him and he kept on stopping it.
We came down from the mountain pass of Adhaakhir in the company of the Messenger of Allah (ﷺ). The time of prayer came and he prayed facing a direction of prayer, and we were (standing) behind him. Then a kid came and passed in front of him. He kept on stopping it until he brought his stomach near the wall (to detain it), and at last it passed behind him, or as Musaddad said.
I was sleeping in front of the Prophet (ﷺ) with my legs between him and the qiblah. Shu'bah said: I think she said: I was menstruating.
Abu Dawud said: This tradition has been narrated by al-Zuhri, 'Ata, Abu Bakr b. Hafs, Hisham b. 'Urwah, 'Irak b. Malik, Abu al-Aswad and Tamim b. Salamah; all transmitted from 'Urwah on the authority of 'Aishah. Ibrahim narrated from al-Aswad on the authority of 'Aishah. Abu al-Duha narrated from Masruq on the authority of 'Aishah. Al-Qasim b. Muhammad and Abu Salamah narrated it from 'Aisha. All these narrators did not mention the words "And I was menstruating."
