Imam Ahmad : 1213

حَدَّثَنَا عَبْد اللَّهِ حَدَّثَنِي مُحَمَّدُ بْنُ بَكَّارٍ حَدَّثَنَا حَفْصُ بْنُ سُلَيْمَانَ يَعْنِي أَبَا عُمَرَ الْقَارِئَ عَنْ كَثِيرِ بْنِ زَاذَانَ عَنْ عَاصِمِ بْنِ ضَمْرَةَ عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ تَعَلَّمَ الْقُرْآنَ فَاسْتَظْهَرَهُ وَحَفِظَهُ أَدْخَلَهُ اللَّهُ الْجَنَّةَ وَشَفَّعَهُ فِي عَشَرَةٍ مِنْ أَهْلِ بَيْتِهِ كُلُّهُمْ قَدْ وَجَبَتْ لَهُمْ النَّارُ

Narrated to us Abdullah, has told me [Muhammad bin Bukair] has told us [Hafsh bin Sulaiman] namely Abu Umar Al Qari', from [Katsir bin Zadan] from ['Ashim bin Dhamrah] from [Ali bin Abu Talib] said : Rasulullah shallallahu 'alaihi wasallam said: "Whoever reads the Qur'an and then masters and memorizes it, Allah will surely admit him to heaven and make him able to intercede for ten people from his family who have been destined to go to Hell.
