In al-Musnad (6/142), from Aishah, may Allah be pleased with her: “Dihyah al-Kalbi resembled Gabriel, peace be upon him, in his beard, bearing, and face.” Its chain is good. It also contains (6/146), through the route of Mujalid, from al-Shabi, from Abu Salamah, from her, that she said: “I saw the Messenger of Allah, may Allah bless him and grant him peace, placing his hand on the mane of a horse while speaking to a man. I said, ‘I saw you placing your hand on the mane of Dihyah al-Kalbi’s horse while speaking to him.’ He said, ‘And did you see him?’ She said, ‘Yes.’ He said, ‘That was Gabriel, peace be upon him, and he conveys greetings of peace to you …’” The hadith. Its chain is good as corroborative evidence. Ibn Sad also recorded something similar through the route of Abdullah ibn Umar, from Yahya ibn Said, from al-Qasim ibn Muhammad, from her, but without the conveying of greetings of peace. Its chain is strong in light of the preceding report.
1112 — “I had been informed of it—that is, Laylat al-Qadr—then it escaped me. So seek it when seven nights remain, or when three nights remain.”
Al-Bazzar recorded it in his Musnad (p. 109—Zawaid of the Maktab al-Islami edition): Yusuf ibn Musa narrated to us; Abdullah ibn al-Jahm narrated to us; Amr ibn Abi Qays (1) narrated to us, from al-Zubayr ibn Adi, from Abu Wail, from Abdullah, who said: “The Prophet, may Allah bless him and grant him peace, was asked about Laylat al-Qadr, and he said”—then he mentioned it.
I say: This is an authentic chain of transmission. All its narrators are trustworthy and are among the narrators mentioned in al-Tahdhib, except Abdullah ibn al-Jahm. Ibn Abi Hatim included his biography (2/2/27) and reported that Abu Zurah said of him: “Truthful.”
Al-Haythami said in al-Majma (3/176): “Al-Bazzar narrated it, and its narrators are trustworthy.”
The hadith has many corroborating reports in the two Sahihs and elsewhere, from a group of the Companions. Some of them may be found in Sahih Abi Dawud (1247, 1248, 1250, 1251, and 1252).
