Hadith 2272ـ عَلِيٌّ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) نِيَّةُ الْمُؤْمِنِ خَيْرٌ مِنْ عَمَلِهِ وَنِيَّةُ الْكَافِرِ شَرٌّ مِنْ عَمَلِهِ وَكُلُّ عَامِلٍ يَعْمَلُ عَلَى نِيَّتِهِ.
2. Ali has narrated from his father from al-Nawfali from al-Sakuni from Abu ‘Abdillah (a.s.) who has said the following: “The Messenger of Allah has said, ‘The intention of the believer is better than his deeds, and the intention of the unbeliever is more wicked than his deeds. Everyone acts according to his intention.’”
