The call for the eclipse prayer is made by saying: "The prayer is a gathering"

Q: The brother M.J. from the United Arab Emirates says in his question: It has been reported that the call for the eclipse prayer is made by saying ("The prayer is a gathering"). Does one say it once, or is it prescribed to repeat it, and what is the extent of the repetition? Please issue a ruling, may Allah reward you.

A: It is established from the Prophet (peace and blessings be upon him) that he ordered the call for the eclipse prayer to be made by saying: It is the Sunnah for the caller to repeat this until he thinks he has made the people hear it, and there is no fixed limit for this, as far as we know. And success is from Allah.
