Answered by Shaykh Faraz Rabbani
As salaamualaikum, I know when and how to perform Sajda Tilawat, but I do not know WHY we perform it. Please advise
Every verse of prostration contains a command to prostrate or severe censure of those who refuse to–thus, believers rush to fulfill this command and to distinguish themselves as those who submit to Allah. The basis of a Divine command is that it establishes an firm duty.
And Allah alone gives success.
