with the Āmīn of the angels will have his past sins forgiven.”
The scholars unanimously agree that saying Āmīn is prescribed for the imam, the congregation, and the person praying alone, and the majority hold that it is recommended, not obligatory.
They have, however, differed over whether it should be voiced aloud or recited silently:
• The Ḥanafīs and Mālikīs consider it preferable to say it quietly, even in prayers that are normally recited aloud.
• The Shāfiʿīs and Ḥanbalīs hold that it should be said aloud in audible prayers and silently in quiet prayers, and that the worshippers’ Āmīn should coincide with the imam’s, citing the hadith, “When he says, {nor those who are astray}, then say Āmīn,” so that their Āmīn and his occur together.
Audible prayers are the first two rakʿahs of Maghrib and ʿIshāʾ, the Dawn prayer, the Friday prayer, the two Eid prayers, the rain-seeking prayer, the eclipse prayer, Tarāwīḥ, and Witr.
3 – In the hadith of Abū Hurayrah the words, “When the imam says Āmīn, then say Āmīn,” mean: when he begins to pronounce it, you pronounce it as well, so that the Āmīn of the imam and of the congregation coincide. The majority of scholars therefore regard this synchronization as recommended, basing themselves on the hadith, “For whoever’s Āmīn coincides with the Āmīn of the angels, his past sins will be forgiven.” [Agreed upon].
