Caution: Translations of Quran and Ḥadīth may lead to possible misapplications and misinterpretations. This site is intended for students of sacred knowledge that are proficient in comprehending classical Arabic and have a strong foundation in Islamic sciences. Also note that religious injunctions rely on several aspects beyond what one may glean through reading individual aḥādīth.
quran:107:1In the name of Allah, the Entirely Merciful, the Especially Merciful.

Have you seen the one who denies the Recompense?  

Have you seen him who denies the Judgement?, the Requital and the Reckoning, that is to say, ‘Do you know who he is?’ If you do not know him then:
القرآن:١٠٧:١بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

أَرَأَيْتَ الَّذِي يُكَذِّبُ بِالدِّينِ  

{أرأيت الذي يُكذِّب بالدين} بالجزاء والحساب، أي هل عرفته وإن لم تعرفه.
