(Important Criterion)
This is to let the minds of those who do not believe in the Hereafter listen to such fabrications, and accept them, and thus expose their real convictions.*
وَلِتَصغىٰ إِلَيهِ أَفـِٔدَةُ الَّذينَ لا يُؤمِنونَ بِالـٔاخِرَةِ وَلِيَرضَوهُ وَلِيَقتَرِفوا ما هُم مُقتَرِفونَ
wa litasghaaa ilaihi af’idatul lazeena laa yu’minoona bil Aakhirati wa liyardawhu wa liyaqtarifoo maa hum muqtarifoon
*6:113 The Quran provides criteria that tell us whether we truly believe in the Hereafter or merely give it lip service. These important criteria are stated here, and in 17:45-46 and 39:45. *6:113-115 Upholding any source beside the Quran reflects disbelief in the Quran (Appendix 18).
