Things that Invalidate Prayer
Q 499: Does testimony concerning the wilayah of the Commander of the Faithful, Imam Ali (a), in the tashahhud invalidate the prayers?
A: The prayer including the tashahhud should be recited in such a way that our great marjis of taqlid (May Allah increase them) mentioned within their books of Practical Laws of Islam and one should not add anything to it even if it is a true and correct phrase.
Q 500: A person is afflicted with riya in his worship and he is now struggling with his self to overcome this riya. Is this also counted as a form of riya? How can he keep away from riya?
A: Any action done for Allah including fighting against riya is not considered riya. To get rid of riya one must think of the greatness of Almighty Allah, the weakness of his own self and his and others dependence on Allah, and his and their subservience to Him, the Exalted.
Q 501: When attending congregational prayers with the Sunni brothers, the word “ammin” is pronounced loudly after the imam finishes reciting the FatiHah. What is the ruling on this?
A: If dissimulation requires saying “ammin” in the said situation, there is no problem in it; otherwise, it is not permissible.
Q 502: In our obligatory prayers is it allowed to say some of the words of the FatiHah, of another chapter or a dhikr in a loud voice in order to warn a child who is doing something dangerous or to make the occupants of the house aware of the situation so that they may remove the danger? In addition, what is the status of the persons prayers during which he, through gestures of the hand or raising of the eyebrows, informs another person of something or answers his question?
A: If the raising of the voice when reciting a verse or dhikr (for the purpose of warning others) does not cause one to lose the status of being in prayer, then there is no objection to doing so, on condition that the recitation and the dhikr are done with the intention of recitation and dhikr. If moving the hand, eyebrows or eye is brief and does not ruin the necessary composure and stillness or the prescribed form of the prayers, it would not lead to invalidation of the prayer.
