(As-Swaffaath) 37 : 157
فَأْتُوا بِكِتَابِكُمْ إِنْ كُنْتُمْ صَادِقِينَ

Then you bring your Book if you are so truthful.

Through this verse, the disbelievers and Mushriks who ascribe partners to Allah and forge lies by ascribing sons, daughters, intercessors, and mediators to Him are challenged to bring evidence from the Lord’s Book to support their claims. Since the 6236 verses of the Lord’s Book are revealed to submit Allah as the only Deity, as explained in verse 2: 255, the Arabic Qur’an reading Fujjar who hold false beliefs about the Lord cannot produce any evidence from any credible Book to support their claims. See explanation 4: 174-175; 17: 55; 21: 24-25.
