Arabic (Original)
حَدَّثَنَا أَبُو مُعَاوِيَةَ حَدَّثَنَا الْأَعْمَشُ عَنْ شِمْرِ بْنِ عَطِيَّةَ عَنِ أَشْيَاخِهِ عَنْ أَبِي ذَرٍّ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَوْصِنِي قَالَ إِذَا عَمِلْتَ سَيِّئَةً فَأَتْبِعْهَا حَسَنَةً تَمْحُهَا قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَمِنْ الْحَسَنَاتِ لَا إِلَهَ إِلَّا اللَّهُ قَالَ هِيَ أَفْضَلُ الْحَسَنَاتِ.
English Translation
Abu Mu'awiyah told us, al-A'mash told us, from Shimr ibn 'Atiyyah, from his shaykhs, from Abu Dharr, who said: I said, "O Messenger of Allah, advise me." He said: "If you do a bad deed, follow it with a good deed which will erase it." I said: "O Messenger of Allah, is 'there is no god but Allah' among the good deeds?" He said: "It is the best of good deeds."
