وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، بَالَ فِي السُّوقِ ثُمَّ تَوَضَّأَ فَغَسَلَ وَجْهَهُ وَيَدَيْهِ وَمَسَحَ رَأْسَهُ ثُمَّ دُعِيَ لِجَنَازَةٍ لِيُصَلِّيَ عَلَيْهَا حِينَ دَخَلَ الْمَسْجِدَ فَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ صَلَّى عَلَيْهَا ‏.‏

Then as soon as he had come into themosque, he was called to pray over a dead person, so he wiped over hisleather socks and prayed. Translation Not Available
