«إذا أمن القارئ فأمنوا فإن الملائكة تؤمن فمن وافق تأمينه تأمين الملائكة غفر له ما تقدم من ذنبه»
(ن ه) عن أبي هريرة.
It is narrated from the words of Abu Huraira, may Allah be pleased with him, that the Prophet (peace and blessings of Allaah be upon him) said:
“When the reciter [1] utters (the word) ‘Amin’, you should also pronounce it, for verily, the angels also say “Amin”!, for if a person’s Amin coincides with the Amin of the angels, his previous sins will be forgiven[2].”
This hadith was narrated by Ahmad 2/238, al-Nasai 2/143, Ibn Majah 852.
Sheikh al-Albani called the hadith authentic. See Sahih al-jami ‘as-saghir 396.
