Whoever suppresses his anger, when he has in his power to show it, God will give him a great reward -Prophet Muhammad (PBUH)
Wisdom from Quran
Allah has promised, to those among you who believe and work righteous deeds, that He will, of a surety grant them in the land, inheritance (of power), as He granted it to those before them; that He will establish in authority their religion -- the one which He has chosen for them; and that He will change (their state), after the fear in which they (lived), to one of security and peace.
They will worship Me (alone) and not associate aught with Me. If any do reject faith after this, they are rebellious and wicked. So establish regular prayer and give regular charity; and obey the apostle; that ye may receive mercy. Never think thou that the unbelievers are going to frustrate (Allah's plan) on earth: their abode is the Fire, -- and it is indeed an evil refuge! - The Holy Qur'an (24: 55-57)
