AsSalamuAlaikum. I have a question about greeting elders.
In our culture, the young bend down a little and bend down their heads to greet their elders and the elders put their hand over the head or the elders put their hand over their head and make a dua (it’s not exactly bowing). I wanted to know if it is permissible Islamically to greet your father, grandfather, etc. by lowering the head Or is it kufr?
