Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Charity does not decrease wealth, no one forgives another but that Allah increases his honor, and no one humbles himself for the sake of Allah but that Allah raises his status.”
Ṣaḥīḥ Muslim
“A man said to the Prophet (Peace Be Upon Him): “Advise me.” He said: “Do not become angry.” The man repeated his request several times, and each time the Prophet (Peace Be Upon Him) told him: “Do not become angry.”
But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment.
“The rights of one Muslim over another are five: returning the greeting, visiting the sick, attending funerals, accepting invitations and saying yarhamukallah (may Allah have mercy on you) when someone sneezes.”
