Muwatta Imam Malik Book of Judgements, Hadith 17
Yahya related to me from Malik from Suhayl ibn Abi Salih as- Samman from his father from Abu Hurayra that Sad ibn Ubada said to the Messenger of Allah ﷺ "What do you think if I find a man with my wife? Shall I grant him a respite until I bring four witnesses?" The Messenger of Allah ﷺ replied, "Yes."
حَدَّثَنَا يَحْيَى، عَنْ مَالِكٍ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ سَعْدَ بْنَ عُبَادَةَ، قَالَ لِرَسُولِ اللَّهِ ﷺ أَرَأَيْتَ إِنْ وَجَدْتُ مَعَ امْرَأَتِي رَجُلاً أَأُمْهِلُهُ حَتَّى آتِيَ بِأَرْبَعَةِ شُهَدَاءَ فَقَالَ رَسُولُ اللَّهِ ﷺ " نَعَمْ " .
