al-Shāfiʿī said in the narration of Harmalah: "We only adopted the timing due to the ḥadīth of al-Muhājir, and it had a sound isnād, and the wiping of the traveler's feet is supported by the ḥadīth of Ṣafwān ibn ʿAssāl." al-Ḥāfiẓ said in "al-Talkhīṣ" (1/157): "And it was also authenticated by al-Khaṭṭābī." It is further strengthened by the ḥadīth of Abū Hurayrah, raised to the Prophet, with the wording: "When one of you puts his feet in his leather socks while they are clean, he should wipe over them..." and the ḥadīth is similar. It was narrated by Ibn Abī Shaybah with a sound isnād from him, and it is included in "al-Ṣaḥīḥah" (1201), and I mentioned under it another path for the ḥadīth of Ṣafwān with a sound isnād from him. On this occasion, I say: As for what was narrated by Ibn Abī Shaybah (1/186) from the path of Ismāʿīl ibn Sumayʿ who said: Abū Razīn told me that Abū Hurayrah said: "I do not care whether I wipe over the top of my leather sock or the back of a donkey!" it is very objectionable, even though the men of its isnād are trustworthy according to Muslim; because the statement of Ibn Sumayʿ from Abū Razīn: "He said: Abū Hurayrah said" appears as a suspended form, so it is feared to be mursal and disconnected. And Ibn Sumayʿ was criticized for his doctrine; as he was from the Ṣufriyyah Khawārij. al-ʿUqaylī narrated (1/79) with a good isnād from Abū Nuʿaym al-Faḍl ibn Dukayn: that he was a neighbor of the mosque for forty years, yet he was not seen in Friday or congregational prayers!
