باب فَضْلِ الذِّكْرِ وَالدُّعَاءِ وَالتَّقَرُّبِ إِلَى اللَّهِ تَعَالَى

حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ ‏.‏ نَحْوَهُ غَيْرَ أَنَّهُ قَالَ ‏"‏ فَلَهُ عَشْرُ أَمْثَالِهَا أَوْ أَزِيدُ ‏"‏ ‏.‏

A hadith like this has been transmitted on the authority of A'mash with the same chain of transmitters and he (further) said:

There is for him ten like that (the good he performed) or more than that.
