Anas bin Malik Al-Ansari (MayAllah be pleased with him) the servant of the Messenger of Allah narrated:
Messenger of Allah (ﷺ) said, "Verily, Allah is more delighted with the repentance of His slave than a person who lost his camel in a desert land and then finds it (unexpectedly)".[Al-Bukhari and Muslim].In another version of Muslim, he said: "Verily, Allah is more pleased with the repentance of His slave than a person who has his camel in a waterless desert carrying his provision of food and drink and it is lost. He, having lost all hopes (to get that back), lies down in shade and is disappointed about his 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 Rubb'.He commits this mistake out of extreme joy".
