I see many people doing during the adhan at the moment when the caller say “ashHadhu anna Muhammadur Rasulullah” they kiss their thumbs nails and they touch their eyes with these. I want to know if it has a proof of Sunnah because I am also doing that. I heard a scholar saying that the prophet Adam was doing like it when Allah swt shows him the appearance of Prophet saw, so if you can give the hadith of it, jazakallahu khair!
Imam Ibn Abidin in his Hashiya and others mentioned that it is medicine
for the eyes and that is enough noteworthy benefit in sha Allah.
