How Should we respond to a backbiter
“Whoever speaks evil about you behind
your back, do not become angry for they
are in reality giving you their good deeds
on a golden plate” - (Imam Hasan Al-Basri).
This is why when he (Imam Hasan) heard
that a man backbite him, he sent him a
gift (a dish of sweets). The man went to
him asking him what was the occasion
for sending him such gift… Imam Hasan
Al Basri answered him :”you backbite me so the dish of sweets was a small gift to
thank you for giving me from your good
deeds” .
May Allah help us to guard our tongue and
limbs from doing things which cause God wrath....Aamiin.
