This was narrated by Abu Dawud (1), Tirmidhi (20), Nasai (17), and Ibn Majah (331), all of them through the route of Muhammad bin Amr, from Abu Salama, from Mughira bin Shuba, in the same wording. Nasai added, "He went to relieve himself during one of his journeys, then said, 'Bring me water for wudu.' So I brought him water, and he performed wudu and wiped over the leather socks." Tirmidhi said, hasan sahih. Ibn Khuzayma (50) and Hakim (1/140) also graded it sahih, both narrating it through the route of Muhammad bin Amr, and Hakim said, "Sahih according to the criteria of Muslim."Its chain is hasan because of Muhammad bin Amr bin Alqama Laythi, Abu Abdullah Madani, one of the leading authorities in hadith. Nasai deemed him trustworthy, and Muslim narrated from him as corroboration, so his standing does not fall below the level of hasan. As for Juzjani, he said, "He is not strong."As for his statement, "when he went to relieve himself" (kana idha dhahaba al-madhhab), with the mim and ha both bearing fatha, and a silent dhal between them, it is a noun of place derived from "going." Abu Ubayda and others said, it is a term for the place of defecation, also called madhhab, khala, marfaq, and mirhad. This is from "Suyuti's commentary on Nasai."
