Passing the Siwak to the older one

 183. Abdullah bin ´Umar narrated that the Messenger of Allah salla alayhi wa sallam said: ´´I saw in a dream that I was using Siwak. Two men grasped me, one of them was elder than the other. I handed the Siwak to the younger man. It was told: ´The elder first.´ So I gave it to the elder.´´
