Prayer: Speaking Loudly or Gesturing During Prayer to Warn Others: Is It Permissible and Is the Prayer Valid?

English:

Question #502:

In our obligatory prayers is it allowed to say some of the words of the Fātiḥah, 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 person’s prayers during which he, through gestures of the hand or raising of the eyebrows, informs another person of something or answers his question?

Answer #502:

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.
