It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The dust that enters a servant's stomach in the way of Allah and the smoke of Hell can never be together; likewise, miserliness and faith can never be together in a servant's heart."

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him) that he said: "Two qualities cannot be combined in a believer: miserliness and bad character."

It is narrated from Abdullah bin Rabee’ah (may Allah have mercy on him) that we were present with Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) when he mentioned a man and also spoke about his character. Sayyiduna Abdullah (may Allah be pleased with him) said: Look! If you cut off his head, can you reattach it? They said: No. He said: Then his hand? They said: No. He said: His leg? They said: No! Sayyiduna Ibn Mas’ud (may Allah be pleased with him) said: When you cannot change his physical form, you cannot change his character either. Indeed, the drop of semen remains in the womb for forty nights, then it becomes a clot of blood, then it becomes a lump of flesh, then Allah Almighty sends an angel who writes down his provision, his character, and whether he will be wretched or blessed.
