Yes, you must at least move your tongue and lips while making the dhikr, dua, salah and recitation of the Qur’an otherwise they’re not valid.

Shaikh,Is it true that prayer is nullified when people read salah with lips closed and not moving their tongue?Does it apply to the daily adhkaar too? should they too be recited audibly or such duas will not be accepted?

A kid near me was running to catch ruku and he tripped, so during salah I saw it and let out a breath of laughter (I did not utter anything though). Do i repeat this asr salah?

Is it correct after we finish Sana – “Allahumma bayid baini – – – -Wal barad” should we say “Auzubillahissamiul A’llim Minash Shaitanir Razim min hamzihi wa nafkhihi wa nafsihi” then “bismillahir Rahmanir rahim”?
