Showing Preference To The One Who Is Older

'Abdullah b. Umar reported that Messenger of Allah ﷺ said: It was shown in a vision that I was rinsing my mouth with miswak and two persons began to contend with one another for getting that miswak. One was older than the other. I gave the miswak to the younger one amongst them, but it was said to me: (Let it be given) to the older one. So I gave it to the older one.

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنِي أَبِي، حَدَّثَنَا صَخْرٌ، - يَعْنِي ابْنَ جُوَيْرِيَةَ - عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " أَرَانِي فِي الْمَنَامِ أَتَسَوَّكُ بِسِوَاكٍ فَجَذَبَنِي رَجُلاَنِ أَحَدُهُمَا أَكْبَرُ مِنَ الآخَرِ فَنَاوَلْتُ السِّوَاكَ الأَصْغَرَ مِنْهُمَا فَقِيلَ لِي كَبِّرْ . فَدَفَعْتُهُ إِلَى الأَكْبَرِ " .
