Character of a Believer: Momin
A believer has been commanded to have patience in every situation. It is forbidden for him to hate anyone. Even if the others commit any oppression or wrong, the command is to tolerate and be patient to the extent of well-wishing and praying for the opponents’ good. These actions of a true believer will make him stronger and win over the hearts of his opponents and enemies.
A person who treats every human interaction as an interaction with God will not commit any excesses in his behaviour.
To curse or pray for the damnation of others is a relinquished practice of the Prophet, whereas well-wishing and presenting the divine message of God is the Prophet’s eternal Sunnah and practice.
