’ In one should say, ‘May Allah grant you blessings.’ If it is repeated then one should say, ‘May Allah forgive you and forgive us.’ The Messenger of Allah was asked if there was a special verse of the Holy Quran about it or something with a mention of Allah. He said, ‘Anything in which there is a mention of Allah is good.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (2/556))
