Question: Assalamu Alaikum Wa Rahmatullahi Wa Barakatuhu
InshaAllah this reaches you in the best of health and Iman Shaykh.
When you are memorizing a surah and there is a Sajdah Tilawah in an ayah, is one required to make sajdah for evertime they read this ayah? Because when memorising you repeat many many times. Is one Sajdah sufficient?
Answer: Wa alaikum assalam wa rahmatullahi wa barakatuh,
I hope you are in the best of health and spirits insha’Allah.
According to the Hanafi school, as long as one recites within a single session (majlis), one only has to perform a single prostration (sajda) at the end.
A session (majlis) can change either:
 Actually (e.g. moving from the kitchen to the living room);
 Effectively (e.g. reading a book, at the dining table, to eating lunch);
For example, if one recited the verse (ayat) fifty times whilst sitting in the living room, it would be sufficient to perform a single prostration.
However, if one recited the verse thirty times in the living room and then twenty times in the kitchen, one would have to perform two prostrations.
