There is no coercion or force with which you can compel any person to have a faith, and this is a response to Takfir, extremism and terrorism. Allah (swt) does not want his servants to have faith by force rather by free will. Allah (swt) cares about hearts not the appearances. If Allah (swt) had willed for all people to believe He would have made them as angels:
{ وَلَوْ شَاءَ رَبُّكَ لَآمَنَ مَن فِي الْأَرْضِ كُلُّهُمْ جَمِيعًا ۚ أَفَأَنتَ تُكْرِهُ النَّاسَ حَتَّىٰ يَكُونُوا مُؤْمِنِينَ}
(And had your Lord willed, those on earth would have believed – all of them entirely. Then, [O Muhammad], would you compel the people in order that they become believers?) (Yunus: 99)
This indicates clearly that the Prophet (saws) has come to direct people and their account is not upon him.
