Sahih Muslim , Hadith 1860 ⓘ

It has been narrated on the authority of Yazid b. Abu Ubaid (the freed slave of Salama b. al-Akwa') who said: 1 asked Salama as to what effect he had sworn fealty to the Messenger of Allah on the Day of Hudaibiya. He said: To the effect that we will die fighting.

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ يَزِيدَ بْنِ أَبِي، عُبَيْدٍ مَوْلَى سَلَمَةَ بْنِ الأَكْوَعِ قَالَ قُلْتُ لِسَلَمَةَ عَلَى أَىِّ شَىْءٍ بَايَعْتُمْ رَسُولَ اللَّهِ صلى الله عليه وسلم يَوْمَ الْحُدَيْبِيَةِ قَالَ عَلَى الْمَوْتِ ‏.‏

The above tradition has also been handed down through a different chain of transmitters.

وَحَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا حَمَّادُ بْنُ مَسْعَدَةَ، حَدَّثَنَا يَزِيدُ، عَنْ سَلَمَةَ، بِمِثْلِهِ ‏.‏
