Amr bin Shu'aib narrates from his father, from his grandfather: The Messenger of Allah (peace and blessings be upon him) said: "If a man's cousin comes to him and asks for something extra and he withholds it from him, Allah Almighty will withhold His grace from him on the Day of Resurrection. And whoever withholds extra water so that he may withhold extra grass through it, Allah will withhold His grace from him on the Day of Resurrection."
