Performing Two Sajdahs Is One of the Foundational Elements
Issue No.944- In every rak‘at after the rukū‘ of the obligatory or recommended prayers, two sajdahs should be performed; if a person, intentionally or forgetfully, omits or adds two sajdahs, his prayer is void. However, if he adds or omits one sajdah forgetfully, his prayer does not become void.
