Hadith 6:911
Ali bin Mushir narrated to us, from al-Shaybani, from Umayr bin Sa'id, who said: I prayed with Ali over Yazid bin al-Mukaffaf. He performed four takbirs over him, then he walked until he reached him and said: "O Allah, Your servant and the son of Your servant has descended upon You today, so forgive him his sin and expand his entrance for him, for we do not know of him except good, and You are more knowing of him than we are."
حدثنا علي بن مسهر عن الشيباني عن عمير بن سعيد قال صليت مع علي على يزيد بن المكفف فكبر عليه أربعا ثم مشى حتى اتاه فقال اللهم عبدك وبن عبدك نزل بك اليوم فاغفر له ذنبه ووسع عليه مدخله فإنا لا نعلم منه إلا خيرا وأنت اعلم به
