It was narrated from Anas that the Messenger of Allah said: “Every son of Adam commits sin, and the best of those who commit sin are those who repent.’”
حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، حَدَّثَنَا عَلِيُّ بْنُ مَسْعَدَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ : " كُلُّ بَنِي آدَمَ خَطَّاءٌ وَخَيْرُ الْخَطَّائِينَ التَّوَّابُونَ " .
