Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
What is our position on kissing our thumbnails and rubbing them on our eyes when the Prophet ﷺ is mentioned during the adhan?
This practice should be given its place, which is that it is the practice of many of the pious people of the Ummah. It cannot be considered an innovation or something prohibited. Likewise it cannot be considered an obligation. We should not make an issue of these things, but rather we should focus on that which is more important and beneficial.
