Hadith 7:114
Anas reported God’s messenger as saying, "All the sons of Adam are sinners, but the best of sinners are those who are given to repentance." Tirmidhi, Ibn Majah and Darimi transmitted it.
وَعَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «كُلُّ بَنِي آدَمَ خَطَّاءٌ وَخَيْرُ الْخَطَّائِينَ التَّوَّابُونَ» . رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ والدارمي
