Sajda-e-tilawat During Salah
It is not compulsory but part of etiquettes of reading Quran and indication of our active relationship with Quran. You can do one sajda whenever such a verse comes in front of you, whether during Salah or reciting Quran elsewhere, and then continue with your regular Salah. For details on Sajda-e-Tilawat , please refer to the videos of Ghamidi Sahab shared in the following thread : Discussion 69323
