Narrated Sahl bin Abu Hathma:

`Abdullah bin Sahl and Muhaiyisa bin Mas`ud bin Zaid went to Khaibar when it had a peace treaty (with the Muslims).

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرٌ، حَدَّثَنَا يَحْيَى، عَنْ بُشَيْرِ بْنِ يَسَارٍ، عَنْ سَهْلِ بْنِ أَبِي حَثْمَةَ، قَالَ انْطَلَقَ عَبْدُ اللَّهِ بْنُ سَهْلٍ وَمُحَيِّصَةُ بْنُ مَسْعُودِ بْنِ زَيْدٍ إِلَى خَيْبَرَ، وَهْىَ يَوْمَئِذٍ صُلْحٌ‏.‏
