We did not perform ablution because of stepping on something impure, nor did we hold back our hair or garments during prayer.
كنا لا نتوضأ من موطي، ولا نكف شعرا ولا ثوبا.
Abu Dawud narrated it (204), and this is his wording. Ibn Majah also narrated it (1041), with the wording, "We were commanded not to gather up our hair or garment, and not to perform wudu because of what we had stepped on." Both are from the hadith of Abdullah bin Idris, and Abu Dawud paired him with Sharik and Jareer, all of them narrating from Amash, from Shaqiq Abu Waail, from Abdullah bin Masud, who related the hadith.Hakim also recorded it (1/171) via the route of Abdullah bin Idris and Abu Bakr bin Abu Shayba, both from Sharik and Jareer, with similar wording, and he said, "Sahih according to the criteria of the two Shaykhs, though they did not include the mention of what was stepped on." He also recorded it (1/139) via the route of Sufyan, from Amash, with the wording, "We used to pray with the Prophet ﷺ and would not perform wudu because of what we had stepped on." He said, "Abu Muawiya and Abdullah bin Idris corroborated him, narrating from Amash with the same wording," and he said, "Sahih according to the criteria of the two Shaykhs."I say, its isnad is hasan, granted that the hasan grading holds on the basis that he heard it from Shaqiq. Otherwise, Ibn Khuzayma said, "This report has a flaw, in that Amash did not hear it from Shaqiq, though I had not grasped this at the time." He then narrated, via the route of Abu Muawiya, from Amash, who said, "Shaqiq narrated to me, or I was told on his authority, from Abdullah." End of quote.I say, if Abu Muawiya expressed doubt about the continuity of the chain, then Abdullah bin Idris, Sharik, and Jareer did not doubt it, all of them narrating it from Amash without any doubt. However, Amash was a mudallis, and he used the ambiguous transmission formula in all these chains, but he falls in the second category according to Ibn Hajar, and the scholars tolerated his tadlis.Tirmidhi mentioned it (143) as a suspended report, saying, "On this subject there is also a report from Abdullah bin Masud, who said, 'We were with the Messenger of Allah ﷺ and we would perform wudu because of what we had stepped on.'" This is the wording of Sufyan bin Uyayna as narrated by Hakim. The Companion's statement, "We were commanded," carries the status of a raised report, because the one who commanded them was the Prophet ﷺ.Khattabi said in his commentary on the hadith, "Al-mawti, what is stepped on, refers to the filth trodden upon on the roads, and its original form is al-mawtu with a waw. What is meant by this is that they did not repeat their wudu because of the filth if it touched their feet, not that they would refrain from washing their feet or cleaning them of filth when it touched them."As for Tirmidhi, he understood from the hadith that "if a man steps on a filthy place, it is not obligatory for him to wash his foot, unless it is wet, in which case he should wash whatever it touched," and he related this from more than one of the people of knowledge, because wet impurity, such as urine and the like, that touches the garment or part of the body and moistens it, cannot simply be left, and nothing purifies it except washing.His statement, "We would not gather up hair or garment," means, we would not protect them from dust when we prayed in order to keep them clean of dust, but rather we would let them fall freely, so that they would touch the ground along with the limbs when we prostrated.
