Question text I have a question regarding ayahs of the Quran when one must perform prostration [sajdah]. Does one have to perform sajdah when one hears these ayahs on the television or radio?
categorization: Qur’an and the Rules
Answer
There are four required [wajeb] sajdahs in the Quran: Chapter 32, (Al-Sajdah) verse 14. Chapter 41 (Fosselat) verse 37. Chapter 53 (Al-Najm), verse 62 Chapter 96 (Al-Alagh), verse 19. If the program is live on the TV or radio, the sajdah is wajeb, but if it is only a CD or a tape, it is not wajeb.
