Question: I left Islam when I was a teenager but al hamduliLlah Allah guided me back to the deen in my 20s. Do I have to make up missed prayers during the time I left Islam?
Answer: Assalamu alaikum wa rahmatullah,
I pray this finds you in the best of health and states.
Alhamdulillah that Allah guided you back to Islam. May Allah keep us and the entire ummah steadfast on the religion, amin.
The answer to your question is no, you do not have to make up those prayers missed during the time of apostasy. [Haskafi/Tumurtashi, Durr al-Mukhtar Sharh Tanwir al-Absar]
And Allah knows best.
