The Messenger of Allah ﷺ said, "May Allah show mercy to a person who prays four rakahs before the Asr prayer."
قال رسول الله ﷺ: رحم الله امرا صلى قبل العصر أربعا.
Abu Dawud (1271) and Tirmidhi (430) both narrated it through Abu Dawud Tayalisi, who said, "Muhammad bin Mihran Qurashi narrated to us, my grandfather Abu Muthanna narrated to me, from Ibn Umar," and he related it.I say, the hadith is in Musnad Abu Dawud Tayalisi (2048), where he said, "Abu Ibrahim Muhammad bin Muthanna narrated to us, from his father, from his grandfather, from Ibn Umar," and he related it similarly, adding the phrase "from his father." This is how it appears in the printed copy.Bayhaqi (2/473) said, after narrating it through Abu Dawud Tayalisi, "This is how I found it in my book." Then he narrated it from Abu Dawud Sijistani as mentioned before, without any mention of "from his father," and said, "This is the correct version." He is Abu Ibrahim Muhammad bin Ibrahim bin Muslim bin Mihran Qurashi, who heard from his grandfather Muslim bin Mihran Qurashi. He is also called Muhammad bin Muthanna, who is the son of Abu Muthanna, because Muslim's kunya was Abu Muthanna. Bukhari mentioned this in al-Tarikh, and said, "As for the statement of the one who said in the first chain 'from his father,' I consider it a mistake. A group narrated it from Abu Dawud without mentioning 'his father,' among them Salama bin Shabib and others." End of quote.I say, the narration of Salama bin Shabib from Abu Dawud was reported by Ibn Khuzayma in his Sahih (1193), from him, from Abu Dawud, without the mention of "his father" in the chain. Its chain is hasan because of Muhammad bin Ibrahim bin Muslim bin Mihran, the muezzin of Kufa, about whom Ibn Main and Daraqutni said, "There is no harm in him," while his grandfather Abu Muthanna was narrated from by a group of scholars, and Abu Zura said, "Trustworthy."I say, Ibn Hibban also graded it sahih (2453), narrating it through Abu Dawud Tayalisi.Hafiz bin Qayyim, may Allah have mercy on him, said, "There has been disagreement about this hadith. Ibn Hibban graded it sahih, while others found fault with it. Ibn Abu Hatim said, 'I heard my father say, I asked Abu Walid Tayalisi about the hadith of Muhammad bin Muslim bin Muthanna, from his father, from Ibn Umar, from the Prophet ﷺ,' and he said, 'Leave that aside.' I said, 'But Abu Dawud has narrated it.' He said, Abu Walid said, 'Ibn Umar used to say, I memorized from the Prophet ﷺ ten rakats during the day and night.' If this were correct, he would have counted it among them." My father said, "He used to say, 'I memorized twelve rakats.'"Hafiz bin Qayyim said, "This is not a defect at all, for Ibn Umar only reported what he had memorized of the Prophet's practice ﷺ, and did not report anything beyond that. So there is no contradiction between the two hadiths whatsoever." End of quote.
