Abraham Lincoln, America's 16th President, said:
"I never read malicious, hostile letters that are sent to me. I never open the envelopes and never bother responding to them. If I were to become busy in dealing with such matters, I would have no time left to do things for my people."
(So turn aside nom them [do not punish them ]...) (Qur'an 4: 63)
(So overlook their faults with gracious forgiveness.) (Qur'an 15: 85)
(So turn away from them [O' Muhammad], and say: Salaam [peace]. (Qur'an 43: 89)
The commander of the American Navy during World War II was a brilliant leader and tactician, and he earned a considerable amount of fame as a result. However, he had to deal with those under his command --- inferiors who harbored jealousy towards him and subordinates who constantly attacked him behind his back with curses and criticism.
And as is usually the case in such instances, he was well aware of what they said about him. He commented on this, saying, "I now have an immunity from criticism. I have become old and am now cognizant of the fact that words cannot destroy greatness, nor can they bring down a sturdy fence."
An Arab poet said:
"What do the poets want from me (through attacking me verbally) And I have past in age the limit of forty."
It has been claimed that 'Eesa (Jesus) (may peace be upon him) said:
"Love your enemy."
The meaning of this saying is that you should give a general pardon to your enemies. This way, you will be free from feelings of revenge, and free from hatred and rancor.
(And those who pardon men; verily Allah loves the good doers.)
(Qur'an 3: 134)
After gaining control of Makkah, the Messenger of Allah (bpuh) said to those who had previously inflicted much harm against him:
"Go forth, for you are the freed ones."
(No reproach on you this days….) (Qur'an 12: 92)
(Allah has forgiven what is past…) (Qur'an 5: 95)
