Hadith 8192

وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " أَيَفْرَحُ أَحَدُكُمْ بِرَاحِلَتِهِ إِذَا ضَلَّتْ مِنْهُ ثُمَّ وَجَدَهَا ؟ " قَالُوا : نَعَمْ يَا رَسُولَ اللَّهِ ، قَالَ " وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ ، لَلَّهُ أَشَدُّ فَرَحًا بِتَوْبَةِ عَبْدِهِ إِذَا تَابَ مِنْ أَحَدِكُمْ بِرَاحِلَتِهِ إِذَا وَجَدَهَا " .
And the Prophet Muhammad (peace be upon him) said: If any one of you loses his mount and after some time finds it again, does he not become happy? The companions (may Allah be pleased with them) replied: Yes, O Messenger of Allah! He said: By Him in Whose hand is the life of Muhammad (peace be upon him), Allah is even more pleased with the repentance of His servant when he repents than the happiness of someone who finds his lost mount.
