Anas ibn Malik says that the Holy Prophet Muhammad said: Allah is more pleased with the repentance of a servant of His than would be one of you, who  were to lose his camel in a barren desert and then find it suddenly (Bokhari and Muslim). The version in Muslim adds: Allah is more pleased with a servant of His than would be one of you who were to lose his riding camel that carries his food and drink, in a barren desert, and losing all hope of finding it he were to lie down in the shade of a tree, and then should suddenly find it standing near him and should seize its nose—string and in his excess of joy blurt out: O Allah, Thou art my servant and I am Thy lord.
