6- وَ حَدَّثَنَا أَبُو الدُّنْيَا مُعَمَّرٌ الْمَغْرِبِيُّ قَالَ حَدَّثَنِي عَلِيُّ بْنُ أَبِي طَالِبٍ ع قَالَ قَالَ رَسُولُ اللَّهِ ص مَنْ قَرَأَ قُلْ هُوَ اللَّهُ أَحَدٌ مَرَّةً فَكَأَنَّمَا قَرَأَ ثُلُثَ الْقُرْآنِ وَ مَنْ قَرَأَهَا مَرَّتَيْنِ فَكَأَنَّمَا قَرَأَ ثُلُثَيِ الْقُرْآنِ وَ مَنْ قَرَأَهَا ثَلَاثَ مَرَّاتٍ فَكَأَنَّمَا قَرَأَ الْقُرْآنَ كُلَّهُ.
Narrated to us Abu Duniya Muammar Maghribi that Ali Ibne Abi Talib said that Holy Prophet صلى الله عليه وعلى آله وسلم said:
“If a person recites Surah Ahad once, it is as if he has recited one-third of Holy Quran. If a person recites it twice, it is as if he has recited two-third of Holy Quran. If a person recites it thrice, it is as if he has recited the entire Holy Quran.”
