Musnad Ahmad 3954

It was narrated that 'Abdullah said: I remember, as soon as the iqamah (call immediately preceding the prayer) was given, the rows would be complete. Whoever would like to meet Allah, may He be exalted, tomorrow as a Muslim, let him regularly offer these prayers where the call to prayer is given, for they (the prayers) are among the ways of guidance and Allah has prescribed the ways of guidance to your Prophet (ﷺ).
