AYATUS SAJDAH (Sajdah during recitation of the Holy QURAAN)
The Prophet (SallAllahu Alaihi Wa Sallam) would offer a Sajdah when during recitation of QURAAN he would come to an ayah where a sajdah is indicated. He would say takbeer and then make prostration. [Za’d -ul- Ma’ad]
Sajdatut – tilawah is wajib
The manner of offering sajdah during recitation is to say Allah-u-Akbar without raising the hands, offer sajdah during which [Subhan-e-Rabbiyal’ala] should be recited three times and then the head should be raised. Note: The pre-requisites for sajdah during recitation are the same as for Salaah i.e. (ablution), neat and clean place, cleanliness of body and dress and facing the Qiblah. [Bahishti Zewar]
