999- وعن ابن مسعودٍ رضي الله عنه ، قَالَ : قَالَ رسولُ اللهِ صلى الله عليه وآله وسلم : "مَنْ قَرَأ حَرْفاً مِنْ كِتَابِ اللهِ فَلَهُ حَسَنَةٌ ، وَالحَسَنَةُ بِعَشْرِ أمْثَالِهَا ، لاَ أقول : ألم حَرفٌ ، وَلكِنْ : ألِفٌ حَرْفٌ ، وَلاَمٌ حَرْفٌ ، وَمِيمٌ حَرْفٌ" رواه الترمذي ، وقال : "حديث حسن صحيح" .
