[Machine] I heard the Messenger of Allah ﷺ saying, "Whenever someone leaves their home in search of knowledge, the angels lower their wings in approval of what they are doing." He was asked about wiping over the socks. He replied, "Yes, I was amongst the army that the Messenger of Allah ﷺ sent, and he commanded us to wipe over our socks three times, for cleanliness, during travel for up to three days and nights, and during staying in a place for one day and one night. We do not take them off except when in a state of major ritual impurity (janabah)." He also said, "I heard the Messenger of Allah ﷺ saying, 'There is a gate open for repentance in the west, the distance of a journey of seventy years, which will not be closed until the sun rises from the west.'"
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَا مِنْ خَارِجٍ يَخْرُجُ مِنْ بَيْتٍ فِي طَلَبِ الْعِلْمِ إِلَّا وَضَعَتْ لَهُ الْمَلَائِكَةُ أَجْنِحَتَهَا رِضًا بِمَا يَصْنَعُ قَالَ جِئْتُ أَسْأَلُكَ عَنِ الْمَسْحِ بِالْخُفَّيْنِ قَالَ نَعَمْ لَقَدْ كُنْتُ فِي الْجَيْشِ الَّذِينَ بَعَثَهُمْ رَسُولُ اللهِ ﷺ فَأَمَرَنَا أَنْ نَمْسَحَ عَلَى الْخُفَّيْنِ إِذَا نَحْنُ أَدْخَلْنَاهُمَا عَلَى طُهْرٍ ثَلَاثًا إِذَا سَافَرْنَا وَيَوْمًا وَلَيْلَةً إِذَا أَقَمْنَا وَلَا نَخْلَعَهُمَا مِنْ غَائِطٍ وَلَا بَوْلٍ وَلَا نَوْمٍ وَلَا نَخْلَعَهُمَا إِلَّا مِنْجَنَابَةٍ قَالَ وَسَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ بِالْمَغْرِبِ بَابًا مَفْتُوحًا لِلتَّوْبَةِ مَسِيرَتُهُ سَبْعُونَ سَنَةً لَا يُغْلَقُ حَتَّى تَطْلُعَ الشَّمْسُ مِنْ نَحْوِهِ
