Repeating Prayers In Case Of Doubt
Since no direct instructions we have from the prophet, Ulama used their Ijtihad to answer these questions. What we learnt from the example of the prophet is, that no matter what mistake we make, sajda sahw compensates it. I hope you have read the passages we posted earlier from the book Meezan on Sajda Sahw. God needs our complete and honest effort. He does not count things like an accountant. You need not to worry at all.
