24فَإِن لَم تَفعَلوا وَلَن تَفعَلوا فَاتَّقُوا النّارَ الَّتي وَقودُهَا النّاسُ وَالحِجارَةُ ۖ أُعِدَّت لِلكافِرينَMuhammad AsadAnd if you cannot do it - and most certainly you cannot do it - then be conscious of the fire whose fuel is human beings and stones1 which awaits all who deny the truth!This evidently denotes all objects of worship to which men turn instead of God - their powerlessness and inefficacy being symbolized by the lifelessness of stones - while the expression "human beings" stands here for human actions deviating from the way of truth (cf. Manar 1,197): the remembrance of all of which is bound to increase the sinner's suffering in the hereafter, referred to in the Qur'an as "hell".
