Q: Assalaamualaikum!When someone is joining in a congregational prayer where the imaam has already gone into the ruku’ posture,does one have to say thanaa after takbeer before proceeding behind imaam,or can u go straight into the posture?
A: Wa alaikum As Salaam,
No, one should not say the Thanaa after the Takbeer. Instead, one should go straight into Ruku after saying the Takbeer.
And Allah Knows Best.
