حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ ، عَنْ الْأَوْزَاعِيِّ ، عَنْ هَارُونَ بْنِ رِيَابٍ ، عَنْ الْأَحْنَفِ بْنِ قَيْسٍ ، قَالَ : دَخَلْتُ مَسْجِدَ دِمَشْقَ ، فَإِذَا رَجُلٌ يُكْثِرُ الرُّكُوعَ وَالسُّجُودَ قُلْتُ : لَا أَخْرُجُ حَتَّى أَنْظُرَ أَيَدْرِي هَذَا عَلَى شَفْعٍ انْصَرِفْتُ أَمْ عَلَى وِتْرٍ فَلَمَّا فَرَغَ، قُلْتُ : يَا عَبْدَ اللَّهِ، أَتَدْرِي عَلَى شَفْعٍ انْصَرَفْتَ أَمْ عَلَى وِتْرٍ؟ فَقَالَ : إِنْ أَكُ لَا أَدْرِي، فَإِنَّ اللَّهَ يَدْرِي.
ثُمَّ قَالَ : إِنِّي سَمِعْتُ خَلِيلِي أَبَا الْقَاسِمِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ :" مَا مِنْ عَبْدٍ يَسْجُدُ لِلَّهِ سَجْدَةً إِلَّا رَفَعَهُ اللَّهُ بِهَا دَرَجَةً، وَحَطَّ عَنْهُ بِهَا خَطِيئَةً ".
قُلْتُ : مَنْ أَنْتَ رَحِمَكَ اللَّهُ؟ قَالَ : أَنَا أَبُو ذَرٍّ .
قَالَ : فَتَقَاصَرَتْ إِلَيَّ نَفْسِي

Muhammad ibn Kathir narrated to us, on the authority of Al-Awza’i, on the authority of Harun ibn Rayyab, on the authority of Al-Ahnaf ibn Qays, who said: I entered the mosque of Damascus, Then I saw a man who was bowing and prostrating a lot. I said: I will not go out until I see whether this is on the basis of intercession. I left or on Witr. So when he finished, I said: Oh. Abdullah, do you know whether you left off on Shafa' or on Witr? He said: If I do not know, then God knows.
Then he said: I heard my friend Abu Al-Qasim, may God’s prayers and peace be upon him, saying: “There is no servant who prostrates before God in a prostration except that God will raise him one degree thereby. And He absolved him of sin thereby.”
I said: Who are you, may God have mercy on you? He said: I am Abu Dharr.
He said: Then my soul came back to me
