“Five kinds of Du'as (invocations), are accepted

The Prophet (SAW) said:

“Five kinds of Du'as (invocations), are accepted:

“The Du'a of an oppressed when he asks for help, Allah helps him;

The Du'a of the Pilgrim until he returns;

And the Du'a of a Mujahid till he returns;

And the Du'a of a sick person until he recovers;

And the Du'a of his brother for a brother in his absence.”

He then said: “The quickest answering Du'a among these is the Du'a of a brother for his brother in his absence”.
