(273) Chapter: Prohibition of Despising Muslims

Jundub bin 'Abdullah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "Once someone said: 'By Allah! Allah will not forgive such and such (a person).' Thereupon Allah, the Exalted and the Glorious, said: 'Who is he who takes an oath in My Name that I will not grant pardon to so-and-so? I have granted pardon to so-and-so and rendered your good deeds fruitless."'

[Muslim].

Commentary: Some people become self-conceited as a result of their excessive worship to the point that they start disparaging and making low estimates of their fellow Muslims and their deeds, little knowing that Allah, Glorious is He, is of vast forgiveness. They do not realize that if Allah so wills, He can destroy all their deeds and consign them to Hell and send the other people who have been disparaged and underestimated to Jannah. Therefore, one should never become proud of his piety nor should one consider others of little value or good deeds, as only Allah Alone knows what is inside our hearts.
