Third Testimony in Tashahhud
Q: Can we say the third testimony in Tashahhud?
A: What is not a part of Tashahhud of obligatory prayers, to say it intending as part of Tashahhud will invalidates one’s prayer. Say your prayer including its Tashahhud in accordance with what great Marji‘s of Sh?‘ah have written in their books of Practical Laws of Islam and do not add any phrase – even a correct and true phrase by itself- to it.
