عَنِ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:" أَرَانِي فِي الْمَنَامِ أَتَسَوَّكُ بِسِوَاكٍ فَجَاءَنِي رَجُلَانِ أَحَدُهُمَا أَكْبَرُ مِنَ الْآخَرِ فَنَاوَلْتُ السِّوَاكَ الْأَصْغَرَ مِنْهُمَا فَقِيلَ لي: كبر فَدَفَعته إِلَى الْأَكْبَر مِنْهُمَا "

‘A'isha said that God’s messenger was using the tooth-stick when two men, one older than the other, were with him. A revelation came to him about the excellence of the tooth-stick in which he was told to show proper respect, and give it to the older of the two. Abu Dawud transmitted it.
