Riyad as-Salihin 351 — The Book of Miscellany

Sahl bin Abu Hathmah Al-Ansari Narrated from:

Abdullah bin Sahl and Muhaiyisah bin Mas'ud (May Allah be pleased with them) went to Khaibar during the period of the truce (after its conquest) and they separated to perform their duties. When Muhaiyisah returned to `Abdullah bin Sahl, he found him murdered, drenched in his blood. So he buried him and returned to Al-Madinah.Then `Abdur-Rahman bin Sahl, Huwaiyisah and Muhaiyisah, the two sons of Mas`ud went to Messenger of Allah (ﷺ) and spoke about the case of their (murdered) friend. `Abdur-Rahman, who was the youngest of them all, started talking. Messenger of Allah (ﷺ) 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 (ﷺ) 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. [Al-Bukhari and Muslim].
