<P> Islam considers itself to be a perfect and final religion . It warns against innovation (bid'ah) to what is revealed in the Quran and the Hadiths . It considers other religions and non-believers in Islam as wrongly guided and infidels . Islam does not recognize and accept spiritual wisdom from other religions . </P> <P> Islam believes in miracles and a final judgment day (Qiyama). Islam believes that there are severe punishments in the afterlife (akhirah) for those who do not submit to Islam, who refuse or reject Islamic teachings, calling them kafir and infidels . Sikhism does not preach or accept this view of those who are not Sikhs . </P> <P> Apostasy, that is abandonment of Islam by a Muslim and conversion to another religion or atheism, is a religious crime in Islam punishable with death . According to the Hadiths, states John Esposito, leaving Islam is punishable by "beheading, crucifixion or banishment", and Sharia (Islamic legal code) traditionally has required death by the sword for an adult sane male who voluntarily leaves Islam . However, adds Esposito, modern thinkers have argued against execution as penalty for apostasy from Islam by invoking Quranic verse 2: 257 . </P> <P> Sikhism allows freedom of conscience and apostasy . </P>
