The ruling on answering the phone and clearing one's throat during prayer

Question:
Honorable Shaykh, may Allah grant you success, during the prayer I answer the phone, clear my throat, and hang up the line to indicate that the person in the house is praying, so that the caller can try again at another time. What is the ruling? And is the ruling

Answer:
If it is without speech, meaning if hanging up the phone is done without speech, or if clearing one's throat is done so that it is understood that you are praying, this is permitted. It is not permitted to clear one's throat in order to alert the one seeking permission to enter. However, if it is with speech, meaning if you answered with speech while you are praying, the prayer is invalidated by this. Yes.
