(1) Its chain of transmission is weak, owing to the poor reliability of Zunfal b. Abd Allah al-Urfi. Ibn Ma'in said of him, "He is nothing"; al-Daraqutni called him "weak," and al-Nasa'i, "not trustworthy." The hadith was also recorded by Abu Bakr al-Marwazi in Musnad Abi Bakr, no. 44; by Abu Ya'la in his Musnad, p. 15; and by al-Tirmidhi, no. 3516 – all through Zunfal. Al-Tirmidhi comments: "This is a gharib hadith; we know it only through Zunfal, who is weak in the eyes of the hadith scholars. He is alone in reporting it and has no corroborator." Al-Nawawi, in al-Adhkar, and Ibn Hajar likewise declared it weak. (2) His biographical notice will appear on p. 247, entry 129. (3) His biography has already been given on p. 163, entry 97. (4) His biographical notice will be given on p. 198, entry 113. (5) For his biography, see: al-Lubab 1/398; Ibar al-Muallif 2/58; Shadharat al-Dhahab 2/171. The nisba "al-Hanini" (with damma on the letter ha, fatha on the nun, and a quiescent ya) is derived from the ancestor Hanin (or Abu Hanin). (6) He is Abu Musa Isa b. Abd Allah b. Sinan b. Dalawayh. The word that follows – written in the base manuscript as "wazghat" – appears with various vocalizations: Tadhkirat al-Huffaz 2/610 has "ra'ab"; the Meccan copy of the same work, "za'ath"; Tarikh Baghdad 11/170, "raghath"; and Shadharat al-Dhahab 2/172, "ghath." No decisive vocalization is given in the specialist works on ambiguous names (kutub al-mushtabih). * His full biography can be consulted in: Tarikh Ibn Asakir, MS 2/213a-214a; Tadhkirat al-Huffaz 2/608-610; al-Ibar 2/65; al-Wafi bi-l-Wafayat 5/346; al-Bidaya wa-l-Nihaya 11/71; Tabaqat al-Qurra' by Ibn al-Jazari 1/11; Lisan al-Mizan 1/48-49; Tabaqat al-Huffaz 269-270; Shadharat al-Dhahab 2/177; Tahdhib Badran 2/208-209. The name "Dayzil" is written with kasra on the dal in the base manuscript, whereas al-Sam'ani – followed by Ibn al-Athir and al-Suyuti – vocalises it with fatha.
