Mu'jam Kabir Tabarani 10507 — the Messenger of Allah ﷺ said: There

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is no faith for one who has no trustworthiness, and no religion for one who does not keep his covenant. By the One in whose hand is the soul of Muhammad, the religion of a servant is not upright until his tongue is upright, and his tongue is not upright until his heart is upright; and one whose neighbour is not safe from his mischief will not enter Paradise." It was said: "O Messenger of Allah, what is his mischief?" He (peace and blessings be upon him) said: "His oppression and injustice. And any man who acquires wealth unlawfully and spends from it will not be blessed in it; if he gives charity from it, it will not be accepted from him; and whatever remains will be his provision for the journey to the Fire. Indeed, the evil does not expiate the evil, but the good expiates the evil."
