The Great Reward of Saying “Āmīn” at the Right Time

Shaykh

From Abū Hurairah, may Allāh be pleased with him, that he said: “The Messenger of Allāh ﷺ said:

When the imam recites:

غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ

And do not make us from those who go down the path of who have [earned] wrath upon themselves—those who knew the truth and did not practice it—the Jews and their like; nor [make us from] those who have gone astray—those who did not seek true guidance, so they went off the [right] path—the Christians and those who followed after their way. (Al-Fātiḥah, 7)

and says after that, “āmīn” [آمين], then say “āmīn,” for indeed, the angels say “āmīn” to his supplication, and anyone whose saying of “āmīn” coincides with the angels’ saying of “āmīn” will have whatever has preceded him of his sins forgiven of him.

Silsilah Al-Ṣaḥīḥah, 2543

When Exactly Should a Follower Say “Āmīn”?

Shaikh Muḥammad Naṣir Al-Dīn Al-Albānī, may Allāh have mercy on him, said:

[…] Indeed, I [once] again draw the attention of all the masses of [people] who pray [in congregation behind an imam] that they pay attention to this sunnah [of trying to say “āmīn” (آمين) at the same time as the angels to attain Allāh’s forgiveness] and to not, [meanwhile], fall into preceding the imam in his saying “āmīn” on account of it. Rather, it is upon them to hold off until, when they hear him pronounce the alif [آ] of āmīn, they [then] say [āmīn] along with him.

Silsilah Al-Ṣaḥīḥah, vol. 6, p. 81
