The final Prophet of God(Sallallaahu `alayhi wa sallam) said,
“Whoever does not argue when he is in the wrong will have a home built for him on the edge of Paradise.
Whoever avoids it when he in the right will have a home built for him in the middle of Paradise.
And whoever improves his own character, a home will be built for him in the highest part of Paradise.”
[Reported in Tirmidhi]
