Do not repeat you salah. This opens the door to waswaas and OCD and a long painful suffering. If there is any mistake in the tajweed, this does not affect your prayer.

iam having this problem that iam doubting my salah , whatever iam reciting in my salah like surahs iam having doubt in them that either iam performing it wrong,however i had some feeling that its right Especially in tajweed,it literally ends up doing my salah one or more than one time ,also i repeat the words one or more time which i feel that i pronounced it wrongly,please help!
