سنن أبي داود

Narrated 'Aishah and Umm Salamah, wives of the Prophet (ﷺ):

The Messenger of Allah (ﷺ) would be overtaken by the dawn when he was in a state of sexual defilement. The narrator 'Abd Allah al-Adhrami said in his version: During Ramadan, due to sexual intercourse and no owing to a dream (i.e. nocturnal emission), and would fast.

Abu Dawud said: How brief is this sentence uttered by the narrator, this is, "he was overtaken by daw when he was in the state of sexual defilement"? The tradition says: The Prophet (ﷺ) was overtaken by dawn in the state of sexual defilement when he was fasting.
