Opposing Allah's disciples leads to Hellfire
Ṣifāt al-Shīʿa|Volume 1|Book 1|Chapter 11
حَدَّثَنَا مُحَمَّدُ بْنُ مُوسَى اَلْمُتَوَكِّلُ قَالَ حَدَّثَنَا عَلِيُّ بْنُ اَلْحُسَيْنِ اَلسَّعْدَآبَادِيُّ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنِ اِبْنِ فَضَّالٍ عَنِ اَلرِّضَا ع أَنَّهُ قَالَ : مَنْ وَالَى أَعْدَاءَ اَللَّهِ فَقَدْ عَادَى أَوْلِيَاءَ اَللَّهِ وَ مَنْ عَادَى أَوْلِيَاءَ اَللَّهِ فَقَدْ عَادَى اَللَّهَ تَبَارَكَ وَ تَعَالَى وَ حَقٌّ عَلَى اَللَّهِ عَزَّ وَ جَلَّ أَنْ يُدْخِلَهُ فِي نَارِ جَهَنَّمَ .
Mohammed bin Musa bin al-Mutawakkil narrated to us from Ali bin al-Hussein as-Sa’dabadi from Ahmed bin Mohammed bin Khalid from Ibn Faddhal that Imam ar-Ridha عليه السلام said: He who follows the enemies of Allah will certainly antagonize the disciples of Allah, and whoever antagonizes the disciples of Allah will antagonize Allah Who will incumbently put him in the fire of Hell.
