Musnad Ahmad 2358
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn 'Abbas (رضي الله عنه) said: A man married an Ansari woman from (the tribe of) Bal’ajlan; he entered upon her and spent the night with her, then the next morning he said: I did not find her to be a virgin. The matter was referred to the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) summoned the girl and asked her, and she said: Yes, I was a virgin. So the Messenger of Allah (ﷺ) instructed them to engage in li'an and he gave her her dowry.
