Question: Assalamu alaykum
I have come to find out there was a time where I have prayed outside of the prayer time thinking I still had time to pray. I prayed and did not make the intention for Qada (making up) since I didn’t know. Would my prayer be valid?
Answer: Wa ‘alaykum as-salam wa rahmatullah wa barakatuh
Thank you for your question.
You can assume that your prayers are valid. What is clear is that you will have had the intention to perform the Maghreb prayer of that day, and this is sufficient after the time has expired to be a valid intention for a qada prayer (Haskafi, al-Durr al-Mukhtar, Ibn Abidin, Radd al-Muhtar).
I recommend that you study the fiqh of prayer in in detail.
May Allah bless you with the best of both worlds.
Wassalam,
