Sahih Muslim 1498a
Abu Huraira (Allah be pleased with him) reported that Sa'd b. 'Ubada al-Ansari said: Messenger of Allah, tell the if a man finds his wife with another person, should he kill him? Messenger of Allah ﷺ said: No. Sa'd said: Why not? I swear by Him Who has honoured you with Truth. There upon Messenger of Allah ﷺ said: Listen to what your chief says.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي الدَّرَاوَرْدِيَّ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ سَعْدَ بْنَ عُبَادَةَ الأَنْصَارِيَّ، قَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ الرَّجُلَ يَجِدُ مَعَ امْرَأَتِهِ رَجُلاً أَيَقْتُلُهُ قَالَ رَسُولُ اللَّهِ ﷺ " لاَ " . قَالَ سَعْدٌ بَلَى وَالَّذِي أَكْرَمَكَ بِالْحَقِّ . فَقَالَ رَسُولُ اللَّهِ ﷺ " اسْمَعُوا إِلَى مَا يَقُولُ سَيِّدُكُمْ ".
