[5]. Be kindly affectioned one to another with brotherly love; in honour preferring one another as the elect of Allāh, righteous and beloved, bowels of mercies, kindness, humbleness of mind, meekness, forbearing one another, and forgiving one another.
The Prophet Muhammad, peace and blessings be upon him, said, “The believer is a mirror to his faithful brother. He protects him against loss and defends him behind his back.”
The believer is a mirror to his brother. If he sees something wrong in him, he should correct it.
