أَبُو مُوسَى تَقَدَّمْ يَا أَبَا عَبْدِ الرَّحْمَنِ فَإِنَّكَ أَقْدَمُ سِنًّا وَأَعْلَمُ قَالَ لَا بَلْ تَقَدَّمْ أَنْتَ فَإِنَّمَا أَتَيْنَاكَ فِي مَنْزِلِكَ وَمَسْجِدِكَ فَأَنْتَ أَحَقُّ قَالَ فَتَقَدَّمَ أَبُو مُوسَى فَخَلَعَ نَعْلَيْهِ فَلَمَّا سَلَّمَ قَالَ مَا أَرَدْتَ إِلَى خَلْعِهِمَا؟ أَبِالْوَادِي الْمُقَدَّسِ أَنْتَ؟ لَقَدْ رَأَيْتُ رَسُولَ اللهِ ﷺ يُصَلِّي فِي الْخُفَّيْنِ وَالنَّعْلَيْنِ
