The Prophet
وَلَوْ كَانُوا يُؤْمِنُونَ بِاللَّهِ وَالنَّبِيِّ وَمَا أُنْزِلَ إِلَيْهِ مَا اتَّخَذُوهُمْ أَوْلِيَاءَ وَلَٰكِنَّ كَثِيرًا مِنْهُمْ فَاسِقُونَ {81}
And had they believed in Allah and the Prophet and what was Revealed to him, they would not have taken them as friends, but most of them are transgressors [5:81]
الَّذِينَ يَتَّبِعُونَ الرَّسُولَ النَّبِيَّ الْأُمِّيَّ الَّذِي يَجِدُونَهُ مَكْتُوبًا عِنْدَهُمْ فِي التَّوْرَاةِ وَالْإِنْجِيلِ يَأْمُرُهُمْ بِالْمَعْرُوفِ وَيَنْهَاهُمْ عَنِ الْمُنْكَرِ وَيُحِلُّ لَهُمُ الطَّيِّبَاتِ وَيُحَرِّمُ عَلَيْهِمُ الْخَبَائِثَ وَيَضَعُ عَنْهُمْ إِصْرَهُمْ وَالْأَغْلَالَ الَّتِي كَانَتْ عَلَيْهِمْ ۚ فَالَّذِينَ آمَنُوا بِهِ وَعَزَّرُوهُ وَنَصَرُوهُ وَاتَّبَعُوا النُّورَ الَّذِي أُنْزِلَ مَعَهُ ۙ أُولَٰئِكَ هُمُ الْمُفْلِحُونَ {157}
Those who are following the Rasool, the Prophet, the Ummy (Makkan) whom they are finding written with them in the Torah and the Evangel (that) he would be instructing them with the good things and forbidding them from the evil, and permitting for them the good things and prohibiting upon them the bad, and removing from them their burdens and their shackles which would be upon them. So those who believe in him, and assist him, and help him, and follow the Light which descends with him, they would be the successful ones [7:157]
محمد بن يعقوب: بإسناده عن أبي عبد الله (عليه السلام)، في قول الله عز و جل: الَّذِينَ يَتَّبِعُونَ الرَّسُولَ النَّبِيَّ الْأُمِّيَّ الَّذِي يَجِدُونَهُ مَكْتُوباً عِنْدَهُمْ فِي التَّوْراةِ وَ الْإِنْجِيلِ يَأْمُرُهُمْ بِالْمَعْرُوفِ وَ يَنْهاهُمْ عَنِ الْمُنْكَرِ وَ يُحِلُّ لَهُمُ الطَّيِّباتِ وَ يُحَرِّمُ عَلَيْهِمُ الْخَبائِثَ- إلى قوله-: وَ اتَّبَعُوا النُّورَ الَّذِي أُنْزِلَ مَعَهُ أُولئِكَ هُمُ الْمُفْلِحُونَ، قال: «النور في هذا الموضع أمير المؤمنين و الأئمة (عليهم السلام)
