The Messenger of Allah ﷺ said, "Three will be upon mounds of musk on the Day of Resurrection. A man who leads a people in prayer while they are pleased with him, a man who calls the five daily prayers every day and night, and a slave who fulfills the right of Allah Almighty and the right of his masters."
حدثنا وكيع عن سفيان عن أبي اليقظان عن زاذان

Its isnad is daif due to the weakness of Abu Yaqzan, as we explained at 3787. Tirmidhi related the hadith, 140-141, and said, a hasan gharib hadith, we do not know it except through the narration of Sufyan, and Abu Yaqzan's name is Uthman bin Qays.We have explained previously that he is Uthman bin Umayr bin Amr bin Qays, so Tirmidhi traced his lineage to his most remote grandfather. See 4673, 4706.
