Reciting a Sūrah Which Contains a Verse of Obligatory Sajdah in Obligatory Prayers
Issue No.899- If a person intentionally recites one of the four sūrahs which contain verses of obligatory sajdah [1] in the prayer, he should, as an obligatory precaution, perform a sajdah instantly upon reciting the verse, then he should stand up and recite al-fātiḥa and the sūrah and finish the prayer, and then repeat the whole prayer. In case it occurs unintentionally and he realises this before reaching the verse of sajdah, he should abandon that sūrah and recite another sūrah. However, if he realises this after he has recited more than half of the sūrah, he should, as an obligatory precaution, repeat the prayer, and if he realises after reciting the verse of obligatory sajdah, he should act as per the above-mentioned instruction (the case of reciting intentionally).
