Al-Dāraqutnī said, “He was a prolific author, trustworthy, and he held the judgeship of the frontier garrisons⦗1⦘.”
Ibn Saʿd states in al-Ṭabaqāt⦗2⦘: “He was reliable, a scholar of ḥadith, and served as the judge of Tarsus, where he died in the year 217 AH.”

(3) Hadith no. 571 in “The Book of Mosques,” chapter “Forgetfulness in prayer and the prostrations that rectify it,” transmitted through the chain Muhammad ibn Ahmad ibn Abi Khalaf – Musa ibn Dawud – Sulayman ibn Bilal – Zayd ibn Aslam – Ata ibn Yasar – Abu Saʿid al-Khudri. The Messenger of Allah ﷺ said: “When any of you is unsure in his prayer and does not know whether he has prayed three or four rakʿahs, he should dismiss the doubt and act on what he is certain of, then perform two prostrations before giving the salam. If he had actually prayed five, the two prostrations will complete his prayer; if he had already prayed four, the two prostrations will humiliate Satan.”
