Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated by Abu Musa (Radi-Allahu ‘anhu):
The Prophet (Sallallahu ‘Alaihi Wa Sallam) heard a man praising another man and he was exaggerating in his praise. The Prophet (Sallallahu ‘Alaihi Wa Sallam) said (to him). “You have destroyed (or cut) the back of the man.”
