Sunan ad-Darimi — Hadith #56109

Muhammad ibn Uyaynah narrated to us, on the authority of Ali ibn Mushar, on the authority of Ash’ath, on the authority of Al-Hasan: “Concerning a man who makes a will for another man, then the person to whom it was made will die. Before the testator, he said: It is permissible for the heirs of the legatee. Muhammad ibn Uyaynah told us, on the authority of Ali ibn Mushar, on the authority of Ash’ath, on the authority of Ubayyah. Ishaq Al-Subaie’i said: I was told that Ali used to allow it like the words of Al-Hasan.
