Dhayyāl said: I saw people whose faces were swollen, or animals with swollen udders, brought to Ḥanẓalah. He would spit onto his hands, say, “In the name of Allah,” place his hand upon his own head, saying, “At the spot touched by the palm of the Messenger of Allah, peace and blessings be upon him,” and then wipe the swollen area with it. Dhayyāl said: The swelling would disappear.
I say: This is an authentic three-narrator chain of transmission. Al-Haythamī said (4/210–211): “Aḥmad narrated it, and its narrators are trustworthy.” I say: Ḥanẓalah was a young Companion for whom the Messenger of Allah, peace and blessings be upon him, supplicated, as you have seen. Dhayyāl was declared trustworthy by Ibn Maʿīn and Ibn Ḥibbān. As for al-Azdī’s statement, “There is something to consider concerning him,” it is, at the very least, not to be given any attention here. Abū Saʿīd, the client of Banū Hāshim, was named ʿAbd al-Raḥmān ibn ʿAbd al-Baṣrī. He was trustworthy and was among al-Bukhārī’s narrators. He was also corroborated by Muḥammad ibn ʿUthmān, who narrated it from Dhayyāl ibn ʿUbayd, though in an abbreviated form of the first part of the account. Al-Ṭabarānī recorded it in al-Muʿjam al-Kabīr (4/15/3499 and 3500). Its narrators, too, are trustworthy, apart from Muḥammad ibn ʿUthmān al-Qurashī, whose standing has already been explained in the preceding hadith.
2956 — “Whoever goes to bed with grease (1) on his hand and is then afflicted by something should blame no one but himself.”
It is narrated from Ibn ʿAbbās, may Allah be pleased with them both, through two chains.
