Verily, Allah is more pleased with the repentance of His slave than a person who has lost his camel in a waterless desert carrying his provision of food and drink. He, having lost all hopes (to get his camel and provisions back), lies down in shade and is disappointed about his (lost) camel; when all of a sudden he finds that camel standing before him. He takes hold of its reins and then out of boundless joy blurts out: 'O Allah, You are my slave and I am Your lord. He commits this mistake out of extreme joy.’

Muslim. Riyad-us-Saliheen (Hadith # 15)
