﴿ وَمَن يَبْتَغِ غَيْرَ ٱلْإِسْلَٰمِ دِينًۭا فَلَن يُقْبَلَ مِنْهُ وَهُوَ فِى ٱلْءَاخِرَةِ مِنَ ٱلْخَٰسِرِينَ ﴾

“For, if one goes in search of a religion other than self-surrender unto God, it will never be accepted from him, and in the life to come he shall be among the lost.”

Not acknowledging any truth external to their community appears to be a bid to save their faith. But in actuality it destroys their faith. God’s true believer lives on God’s continuous inspiration, so that one who confines himself to self-worship and community-worship will be blocking all paths to God’s blessing entering into him. After being deprived of God’s inspiration, what will there be left with which to nurture his faith?
