لا يَسَعُكُمْ فِيمَا يَنْزِلُ بِكُمْ مِمَّا لا تَعْلَمُونَ إِلا الْكَفُّ عَنْهُ وَالتَّثَبُّتُ وَالرَّدُّ إِلَى أَئِمَّةِ الْهُدَى حَتَّى يَحْمِلُوكُمْ فِيهِ عَلَى الْقَصْدِ وَيَجْلُوا عَنْكُمْ فِيهِ الْعَمَى وَيُعَرِّفُوكُمْ فِيهِ الْحَقَّ قَالَ الله تَعَالَى فَسْئَلُوا أَهْلَ الذِّكْرِ إِنْ كُنْتُمْ لا تَعْلَمُونَ.

‘In the case of what may come to you and you have no knowledge of its veracity you can do nothing but to hold and verify and refer it to the Imams of guidance so that he would show the way of justice in it and enlighten you in the darkness and introduce to you the truth. Allah, the Most High has said, “Ask those who know about the heavenly Books if you do not know about this.”’’ (16:43)
