“Allah rejoiced more over the repentance of anyone of you, then you rejoice over your lost animal when you find it.”  

ابن ماجة:٤٢٤٧ – حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا شَبَابَةُ حَدَّثَنَا وَرْقَاءُ عَنْ أَبِي الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ اللَّهَ ﷻ أَفْرَحُ بِتَوْبَةِ أَحَدِكُمْ مِنْهُ بِضَالَّتِهِ إِذَا وَجَدَهَا

Allah is more pleased with the repentance of His servant when he turns penitently towards Him than one of you would be on finding the lost camel.  

مسلم:٢٦٧٥i – حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ الْقَعْنَبِيُّ حَدَّثَنَا الْمُغِيرَةُ يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْحِزَامِيَّ عَنْ أَبِي الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ لَلَّهُ أَشَدُّ فَرَحًا بِتَوْبَةِ أَحَدِكُمْ مِنْ أَحَدِكُمْ بِضَالَّتِهِ إِذَا وَجَدَهَا
