عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ وَالَّذِي نَفْسِي بِيَدِهِ أَوْ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوْ أَخْطَأْتُمْ حَتَّى تَمْلَأَ خَطَايَاكُمْ مَا بَيْنَ السَّمَاءِ وَالْأَرْضِ ثُمَّ اسْتَغْفَرْتُمُ اللَّهَ عَزَّ وَجَلَّ لَغَفَرَ لَكُمْ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ أَوْ وَالَّذِي نَفْسِي بِيَدِهِ لَوْ لَمْ تُخْطِئُوا لَجَاءَ اللَّهُ عَزَّ وَجَلَّ بِقَوْمٍ يُخْطِئُونَ ثُمَّ يَسْتَغْفِرُونَ اللَّهَ فَيَغْفِرُ لَهُمْ
Narrated by Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: By Him in Whose hand is the life of Muhammad (peace and blessings be upon him)! If you continue to commit sins until the space between the earth and the sky is filled because of your sins, then you seek forgiveness from Allah, He will forgive you. By Him in Whose hand is my life! If you do not commit sins, Allah will create people who will commit sins, then they will seek forgiveness from Allah, and He will forgive them.
