حَدَّثَنَا سُرَيْجٌ حَدَّثَنَا عَبْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّهُ كَانَ يُصَفِّرُ لِحْيَتَهُ وَيَلْبَسُ النِّعَالَ السِّبْتِيَّةَ وَيَسْتَلِمُ الرُّكْنَيْنِ وَيُلَبِّي إِذَا اسْتَوَتْ بِهِ رَاحِلَتُهُ وَيُخْبِرُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَفْعَلُهُ
مسند امام احمد بن حنبل · Hadith 5950
It was narrated from Ibn 'Umar that he used to dye his beard with sufrah (henna), wear sandals of tanned leather, touch the two corners (of the Ka'bah), and recite the Talbiyah when his mount rose up with him, and he used to say that the Prophet (PBUH) used to do these things.
