'Abdullah bin 'Umar (May Allah be pleased with tehm) reported:
The Prophet (ﷺ) said, "It was shown to me in my dream that I was cleaning my teeth with a Miswak and two men came to me, one being older than the other. I gave the Miswak to the younger one, but I was asked to give it to the older, which I did".[Al-Bukhari and Muslim].
