وعن أبي يحيى وقيل
أبي محمد سهل بن أبي حَثْمة بفتح الحاء المهملة وإسكان الثاء المثلثة الأنصاري رضي الله عنه قال: انطلق عبد الله ابن سهل ومحيصة بن مسعود إلى خيبر وهي صلح، فتفرقا، فأتى محيصة إلى عبد الله بن سهل وهو يتشحط في دمه قتيلاً، فدفنه، ثم قدم المدينة فانطلق عبد الرحمن بن سهل ومحيصة وحويصة ابنا مسعود إلى النبي صلى الله عليه وسلم، فذهب عبد الرحمن يتكلم فقال: «كبر كبر«وهو أحدث القوم، فسكت، فتكلما فقال: «أتحلفون وتستحقون قاتلكم؟ وذكر تمام الحديث»
Abdullah ibn Sahl and Muhaiyisah ibn Masud (radiyallahu anhum) went to Khaibar during the period of the truce (after its conquest) and they separated to perform their duties. When Muhaiyisah returned to Abdullah ibn Sahl, he found him murdered, drenched in his blood. So he buried him and returned to Al-Madinah. Then Abdur-Rahman ibn Sahl, Huwaiyisah and Muhaiyisah, the two sons of Masud went to Messenger of Allah (sallallahu alayhi wa sallam) and spoke about the case of their (murdered) friend.
Abdur-Rahman, who was the youngest of them all, started talking. Messenger of Allah (sallallahu alayhi wa sallam) said, “Let those older than you speak first.” So he stopped talking and the (other two) spoke about the case of their (murdered) friend.
Messenger of Allah (sallallahu alayhi wa sallam) said, “Will you take an oath whereby you will have the right to receive the blood money of your murdered man?” And mentioned the rest of the Hadith.
