(1) See Ibn Abi Shaybah, al-Musannaf, where he records the report from both transmitters with his own chain in the Book of Prayer, chapter “Those who regarded letting the garment hang (sadl) during prayer as disliked,” 2:259. (2) Sulayman ibn Abi Sulaym al-Makki, known as al-Ahwal. Ahmad, Ibn Maʿin, al-Nasaʾi and others judged him reliable, and all six canonical compilers narrated from him. He belongs to the fifth generation of transmitters. See: Tahdhib al-Tahdhib 4:218, no. 368; Taqrib al-Tahdhib 1:330, no. 492. (3) In MS Ṭ the text reads: “and Ali ibn Sufyan,” which is a scribal corruption of ʿAsal. (4) ʿAsal ibn Sufyan al-Tamimi al-Yarbuʿi, Abu Qurrah al-Basri. Ibn Maʿin and Ahmad deemed him weak; Ibn Saʿd, al-Bukhari and al-Nasaʾi also criticized him, though Ibn Hibban listed him among the trustworthy, remarking: “He makes mistakes and contradicts others, despite narrating little.” Tahdhib al-Tahdhib 7:194, no. 369. (5) The hadith is transmitted by: • Abu Dawud, Book of Prayer, “Reports on sadl in prayer,” no. 643 (1:423); • al-Tirmidhi, Book of Prayer, “Dislike of sadl in prayer,” no. 378 (2:217); • Ahmad, al-Musnad 2:295, 341. Al-Tirmidhi and Ahmad omit the clause about covering the mouth. Al-Hakim also narrates it in al-Mustadrak from Sulayman al-Ahwal, from ʿAtaʾ, from Abu Hurayrah, from the Prophet, and comments: “This chain is authentic according to the criteria of the Two Shaykhs, yet they did not record the wording about a man covering his mouth while praying.” Al-Mustadrak 1:253. (6) ʿAmir ibn ʿAbd al-Wahid al-Ahwal al-Basri. Ibn Hajar writes: “Trustworthy, though he errs; sixth generation.” Ahmad said: “He is not strong in hadith,” Ibn Maʿin: “There is no harm in him,” and Abu Hatim: “Reliable, unobjectionable.” See: Taqrib al-Tahdhib 1:389, no. 59ʿ; al-Jarh wa-l-Taʿdil 6:326–27, no. 1817.
