Once Jibreel alai his Salaam came to rasoolullah sallallahu alaihi wasallam while he was climbing Minbar and asked him to say AAMEEN three times.
What were those three duas which Jibreel alai his Salaam made?
It was narrated that Abu Hurayrah (may Allaah be pleased with him) said:
The Prophet (peace and blessings of Allaah be upon him) ascended the minbar and said: Aameen, aameen, aameen.”Thrice
It was said: ‘O Messenger of Allaah, you ascended the minbar and said,‘Aameen, AAMEEN, aameen.”He said:
Jibreel (peace be upon him) came to me and said:
1)‘If Ramadaan comes and a person is not forgiven, he will enter Hell and Allaah will cast him far away. Say Aameen.’ So I said AAMEEN
2) He said:‘O Muhammad, if both or one of a person’s parents are alive and he does not honour them and he dies, he will enter Hell and Allaah will cast him far away. Say AAMEEN. So I said AAMEEN
3) He said:‘If your Name Muhammad mentioned in a person’s presence and he does not send blessings upon you and he dies, he will enter Hell and Allaah will cast him far away. Say AAMEEN. So I said AAMEEN
