Abdullah bin 'Umar reported Allah's Messenger (ﷺ) as saying: I saw in a dream that I was using miswak and the two persons contended to get it from me, the one being older than the other one. I gave the miswak to the younger one. It was said to me to give that to the older one and I gave it to the older one.

Hadith Commentary: Benefits and Issues:
From this hadith, it is understood that when giving something, one should take into account the status, rank, and position of people.
The miswak (tooth-stick) is needed by the elder.
In invitations for food and drink, elders will be given precedence.
However, if in a gathering both elders and youngsters are seated, then the beginning will be made from the right side,
regardless of whether the person sitting on that side is younger or older.
