وَ قَالَ عَزَّ وَ جَلَ لا تَجِدُ قَوْمًا يُؤْمِنُونَ بِاللهِ وَ الْيَوْمِ الْآخِرِ يُوادُّونَ مَنْ حَادَّ اللهَ وَ رَسُولَهُ وَ لَوْ كانُوا آباءَهُمْ اَوْ اَبْناءَهُمْ اَوْ اِخْوانَهُمْ اَوْ عَشِيرَتَهُمْ وَ قَالَ عَزَّ وَ جَلَ وَ لا تَرْكَنُوا اِلَى الَّذِينَ ظَلَمُوا فَتَمَسَّكُمُ النَّارُوَ الظُّلْمُ هُوَ وَضْعُ الشَّيْءِ فِي غَيْرِ مَوْضِعِهِ فَمَنِ ادَّعَى الْاِمَامَةَ وَ لَيْسَ بِاِمَامٍ فَهُوَ الظَّالِمُ الْمَلْعُونُ وَ مَنْ وَضَعَ الْاِمَامَةَ فِي غَيْرِ اَهْلِهَا فَهُوَ ظَالِمٌ مَلْعُونٌ.
Allah – Mighty and Majestic be He – said, “You shall not find a people who believe in Allah and the latter day befriending those who act in opposition to Allah and His Apostle, even though they were their (own) fathers, or their sons, or their brothers, or their kinsfolk…” and He – Mighty and Majestic be He – said, “And do not incline to those who are unjust, lest the fire touch you…”And injustice means to put a thing in its inappropriate place. Thus, whoever claims Imamate while he is not an Imam (from the side of Allah) is unjust and accursed. And whoever believes in an Imam who is not eligible for that post is unjust and accursed.”
