The call to the eclipse prayer should be made by saying “Al-Salaatu jaami’ah”
Question

It is narrated that the call to the eclipse prayer should be made by saying “Al-Salaatu jaami’ah”. Should this be said once, or is it prescribed that it should be repeated? How often should it be repeated? Please advise us, may Allah reward you.
Praise be to Allah.It was reported that the Prophet (peace and blessings of Allah be upon him) gave orders that the call to the eclipse prayer should be made by saying “Al-Salaatu jaami’ah”. This was narrated by al-Bukhaari and Muslim.  The Sunnah is for the caller to repeat that until he thinks that the people have heard; there is no set limit for that as far as we know. And Allah is the Source of strength.
