(23) باب قَوْلِهِ " رَبَّنَا وَلَكَ الْحَمْدُ "
It was narrated from Abu Hurairah that:
The Messenger of Allah (ﷺ) said: "When the Imam says: 'Sami Allahu liman hamidah (Allah hears the one who praises Him),' then say: 'Rabbana wa lakal-hamd,' (Our Lord, and to You be the praise).' Whoever says that and it coincides with the angels saying it, his previous sins will be forgiven." (JA)
