The Holy Prophet ﷺ said that if a person forgives another person, then Allah Ta’ala will forgive him on the day he will need forgiveness most (the Day of Qiyamah).
In Quran Karim Allah Ta’ala says;
“And if one observes patience and forgives, it is, of course, one of the courageous conducts.” (42:43)
In another verse the Holy Quran says;
“Repel (evil) with what is best, and you will see that the one you had mutual enmity with will turn as if he were a close friend.” (41:34)
And in the very next verse adds,
“And no one is blessed with this (attitude) but those who observe patience, and no one is blessed with this (attitude) but a man of great luck.” (41:35)
Once Hazrat Abu Bakr Siddiq (may Allah Ta’ala be pleased with him) became angry with his slave. He uttered some words cursing that slave under the influence of that anger. The Holy Prophet ﷺ who was coming from behind, heard that curse. He said,
“You are a Siddiq and you curse too. I swear upon the God of Ka’abah that this can’t be.”
As soon as Hazrat Abu Bakr Siddiq RAA heard the Holy Prophet ﷺ say that a Siddiq does not curse, he immediately said, “O Prophet of Allah ﷺ. I grant this slave his freedom.”
In a Hadith, the Holy Prophet ﷺ said to Hazrat Aisha (may Allah Ta’ala be pleased with her),
“Softness makes everything beautiful, while if softness is taken out of something this makes it flawed.”
In the characteristics of the Holy Prophet ﷺ mentioned in Torah and Inji’l, one of the sentences is,
“He will neither be vulgar, nor will he use foul language, he won’t be one of those who raise their voices in the Bazar, rather he will be forgiving and forbearing.”
