وَعَنْهُ أَيْضًا أَنَّهُ سَافَرَ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَدَخَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَادِيًا فَقَضَى حَاجَتَهُ ثُمَّ خَرَجَ فَأَتَاهُ فَتَوَضَّأَ فَخَلَعَ خُفَّيْهِ فَتَوَضَّأَ فَلَمَّا فَرَغَ وَجَدَ رِيحًا بَعْدَ ذَلِكَ فَعَادَ فَخَرَجَ فَتَوَضَّأَ وَمَسَحَ عَلَى خُفَّيْهِ، فَقُلْتُ: يَا نَبِيَّ اللَّهِ! نَسِيتَ لَمْ تَخْلَعِ الْخُفَّيْنِ؟ قَالَ: ((كَلَّا، بَلْ أَنْتَ نَسِيتَ، بِهَذَا أَمَرَنِي رَبِّي عَزَّ وَجَلَّ))
It is narrated from Sayyiduna Mughirah (may Allah be pleased with him) that he traveled with the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) entered a valley, relieved himself, then came out and performed ablution near me. He removed his leather socks (khuffs) and performed ablution. But when he finished, he felt some wind (in his stomach), so he returned again. Then he came back and performed ablution again, but this time he wiped over his socks. I said: O Messenger of Allah! Did you forget not to remove your socks? The Prophet (peace and blessings be upon him) replied: No, by no means; rather, you have forgotten. My Lord has commanded me to wipe over them in this manner.
