Abu Huraira reported Allah's Messenger (ﷺ) as saying:

Observe moderation in deeds (and if it is not possible, try to be near moderation) and understand that none amongst you can attain salvation because of his deeds alone. They said: Allah's Messenger (ﷺ) , not even you? Thereupon he said: Not even I, but that Allah should wrap me in His Mercy and Grace.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ قَارِبُوا وَسَدِّدُوا وَاعْلَمُوا أَنَّهُ لَنْ يَنْجُوَ أَحَدٌ مِنْكُمْ بِعَمَلِهِ ‏"‏ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ وَلاَ أَنْتَ قَالَ ‏"‏ وَلاَ أَنَا إِلاَّ أَنْ يَتَغَمَّدَنِيَ اللَّهُ بِرَحْمَةٍ مِنْهُ وَفَضْلٍ ‏"‏ ‏.‏
