(9) Ja‘far b. Muhammad reports from his father, in a mursal and marfu form: “Pronounce tasbih three times while bowing and three times while prostrating.” It was recorded by al-Bayhaqi (2/86), who commented, “This is mursal.” In addition, verbal reports corroborate these practical narrations. Among them is the hadith attributed to Ibn Mas‘ud: “When any of you bows and, while bowing, says: Subhana Rabbi al-Azim (Glory be to my Lord, the Supreme) three times, his ruku is complete and that is its minimum; and when he prostrates and, while prostrating, says: Subhana Rabbi al-A‘la (Glory be to my Lord, the Most High) three times, his sujud is complete and that is its minimum.” It was transmitted by Abu Dawud (1/141), al-Tirmidhi (2/46–47), Ibn Majah (1/289), al-Shafi‘i in al-Umm (1/96), al-Tahawi (1/136), al-Daraqutni (131), and al-Bayhaqi (2/86, 110) through Ibn Abi Dhiʿb, from Ishaq b. Yazid al-Hudhali, from Awn b. ʿAbd Allah b. ʿUtbah, from Ibn Mas‘ud. Abu Dawud, al-Tirmidhi, and al-Bayhaqi regarded it defective because Awn b. ʿAbd Allah did not hear from Ibn Mas‘ud, leaving a gap in the chain. I add another flaw: the narrator Ishaq b. Yazid al-Hudhali is unknown. In Nayl (2/208) al-Shawkani cites Ibn Sayyid al-Nas: “We do not know anyone who declared him reliable, and he is known only through the narration of Ibn Abi Dhiʿb; therefore both his personal and circumstantial anonymity remain.” Al-Hafiz states in Taqrib al-Tahdhib, “Unknown.”
