Is it permissible to interrupt my prayer to answer my brother if he is in a great hurry and cannot wait, or should I continue my prayer?

Question:
He asks and says: If I have started the prayer, and suddenly my brother arrives and asks me about things, and he is very busy and in a great hurry and cannot wait, do I interrupt the prayer and speak to him? Or do I continue my prayer while he waits?

Answer:
It is not permissible for you to interrupt the prayer; rather, it is obligatory for you to continue your prayer, and your brother waits for you until you complete the prayer, or he leaves and comes at another time. As for interrupting the prayer for that reason, it is forbidden. Allah the Exalted said: It is only permissible to interrupt the prayer in a case of danger, such as saving a person from destruction if you left him and continued the prayer, he would perish, such as if he were to fall into a fire, or drown, or fall into a well, or something else, and you save him. In that case, there is no harm in interrupting the prayer for it, because this is a case of dire necessity to save a protected person from destruction. As for answering the questioner, this is not necessary and has another time. Yes.
