Hadith 6:693
Hafs ibn Ghiyath narrated to us, from Hajjaj, from Umayr ibn Sa'id, who said: Ali prayed over Yazid ibn al-Mukaffaf. He performed four takbirs over him and performed one quiet taslim to his right.
حدثنا حفص بن غياث عن حجاج عن عمير بن سعيد قال صلى علي على يزيد بن المكفف فكبر عليه اربعا وسلم تسليمة خفية عن يمينه
