The following verse clearly explains the superiority of Islam over all religions past and present. Allah declares,
وَمَن يَبْتَغِ غَيْرَ الْإِسْلَامِ دِينًا فَلَن يُقْبَلَ مِنْهُ وَهُوَ فِي الْآخِرَةِ مِنَ الْخَاسِرِينَ
“If anyone desires a religion other than Islam, never will it be accepted of him; and in the Hereafter, he will be in the ranks of those who have lost (all spiritual good).”
(The Holy Quran, Chapter of Ale’ Imran, verse 85)
This verse decrees the establishment of Islam as the final religion of Allah. This verse invalidates all new religions that appeared after Islam like, Sikhism, Qadianism and Bahaism. Thus the doors of prophethood were closed on all future claimants, thereby establishing the finality of Islam as well as that of the Holy Prophet (p.b.u.h).
