Abu Hurairah narrated that the Messenger of Allah said:: "The Muslim is the brother to the Muslim, he does not cheat him, lie to him, nor deceive him. All of the Muslim is unlawful to another Muslim: His Honor, his wealth, and his blood. At-taqwa is here. It is enough evil for a man that he belittle his brother Muslim
