Don't despair from the mercy of Allah

narrated in Saheeh Muslim (2744) from Anas ibn Maalik (may Allaah be pleased with him) who said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Allaah rejoices more over the repentance of His slave when he repents to Him than one of you who was on his mount in the wilderness, then he lost it, and his food and drink are on it, and he despairs of finding it. He goes to a tree and lies down in its shade, having lost hope of finding his mount, and whilst he is like that, there it is standing in front of him, so he takes hold of its reins and says, because of his intense joy, ‘O Allaah, You are my slave and I am your lord,’ making this mistake because of his intense joy.”
