Jews Envy Us In 2 Things
The Messenger of Allah ( peace and blessings of Allaah be upon him ) said:
“Indeed, the Jews envy you because of your greeting ( salaam ) and saying” Amin “.” See Saheeh al-Jami 1997.
Shaykh al-Albani said: “In this Hadith it is an indication that it is Sunnah for those who follow the Imam to pronounce aloud “Amin” since pronouncing this aloud increases the anger of the Jews and arouses them envy in the same way as Salam, as this is evident from the Hadith. So think about it ” See al-Sahiha” 2/314.
