Assalamuwalikum What is your opinion with regarding creating a symbol (round) like black at forehead dor doing Sajda?
Answer:
(Fatwa: 1616/1533=D/1429)
If the impression was naturally created due to excessive sajdah (prostration), then it will be a cause of reward, in-sha-Allah.
Allah (Subhana Wa Ta’ala) knows Best
