[Machine] Abu Musa stepped forward and said, "O Abu Abdur Rahman, you should go ahead, for you are older and more knowledgeable." He replied, "No, you should go ahead, for we have come to you in your house and mosque." So Abu Musa preceded him and took off his shoes. When he finished praying, Abu Abdur Rahman asked him, "Why did you take off your shoes? Did you see the Prophet ﷺ do so?"
لَهُ أَبُو مُوسَى تَقَدَّمْ يَا أَبَا عَبْدِ الرَّحْمَنِ فَإِنَّكَ أَقْدَمُ سِنًّا وَأَعْلَمُ قَالَ لَا بَلْ تَقَدَّمْ أَنْتَ فَإِنَّمَا أَتَيْنَاكَ فِي مَنْزِلِكَ وَمَسْجِدِكَ فَتَقَدَّمَ أَبُو مُوسَى فَخَلَعَ نَعْلَيْهِ فَلَمَّا صَلَّى قَالَ مَا أَرَدْتَ إِلَى خَلْعِهَا أَبِالْوَادِ الْمُقَدَّسِ طُوًى أَنْتَ؟ لَقَدْ «رَأَيْتُ رَسُولَ اللهِ ﷺ يُصَلِّي فِي الْخُفَّيْنِ وَالنَّعْلَيْنِ»
