In Quran, Allah The Almighty said: “Indeed, performing prayers is a duty on the believers at the appointed times.” [4:103]. All obligatory prayers must be performed within a certain period of time. If, for any reason, prayer is not performed at the appointed time, it should be performed as soon as possible, observing the rules for performing haza-namaz. Completing a prayer that was not performed on time is mandatory, as are the fivefold prayers themselves.
