Al-Hakim (1/266)—and, citing him, al-Bayhaqi (2/142)—narrate it through several chains from Ayman b. Nabil, from Abu al-Zubayr, from him, with the additional phrase: “In the name of Allah, and by Allah, at-tahiyyat …,” and so forth. Ahmad (5/363) transmits the same route, but he neither names the Companion nor mentions the addition. Al-Hakim—followed by al-Dhahabi—ruled: “Authentic according to al-Bukhari’s criteria.” That judgment is unfounded, for Ayman b. Nabil appears in al-Bukhari only as a corroborating narrator, as stated in Tahdhib. The leading scholars have further declared him mistaken here because he says, “from Abu al-Zubayr, from Jabir,” whereas the correct chain is “from Abu al-Zubayr, from Tawus and Sa id b. Jubayr, from Ibn Abbas,” as noted earlier. They also faulted him for inserting the basmalah into the tashahhud. Al-Nawawi remarks in al-Majmu (3/457): “According to the hadith specialists, this report is weak, as the author and al-Baghawi relate; among those who weakened it are al-Bukhari and al-Nasai.” He adds: “Al-Hakim’s claim of authenticity is unacceptable, for the scholars who graded it weak are stronger authorities and more precise than he.” Al-Hafiz Ibn Hajar treats the hadith at length in al-Talkhis (3/512–13); the interested reader may consult it. (1) From Ibn Masud (may Allah be pleased with him): “Part of the sunnah is that the tashahhud be recited quietly.”
