وَإِذَا قِيلَ لَهُمْ اتَّبِعُوا مَا أَنزَلَ اللَّهُ قَالُوا بَلْ نَتَّبِعُ مَا أَلْفَيْنَا عَلَيْهِ آبَاءَنَا أَوَلَوْ كَانَ آبَاؤُهُمْ لاَ يَعْقِلُونَ شَيْئًا وَلاَ يَهْتَدُونَ﴾ ﴿بَلْ قَالُوا إِنَّا وَجَدْنَا آبَاءَنَا عَلَى أُمَّةٍ وَإِنَّا عَلَى آثَارِهِمْ مُهْتَدُونَ وَكَذَلِكَ مَا أَرْسَلْنَا مِنْ قَبْلِكَ فِي قَرْيَةٍ مِنْ نَذِيرٍ إِلاَّ قَالَ مُتْرَفُوهَا إِنَّا وَجَدْنَا آبَاءَنَا عَلَى أُمَّةٍ وَإِنَّا عَلَى آثَارِهِمْ مُقْتَدُونَ قَالَ أَوَلَوْ جِئْتُكُمْ بِأَهْدَى مِمَّا وَجَدْتُمْ عَلَيْهِ آبَاءَكُمْ قَالُوا إِنَّا بِمَا أُرْسِلْتُمْ بِهِ كَافِرُونَ
This is why Islam demands sound convictions and opposes blind imitation. Every person who is duly qualified as a genuine and earnest thinker is enjoined by Islam to employ his faculties to the fullest extent. But if a person is unqualified or uncertain of himself, he should pursue his thinking only as far as his limits can take him. It will be quite in order for such a person to rely only on the authentic sources of religion, which are sufficient in themselves, without applying to them any critical questioning of which he is incapable. The point is that no one can call himself a true Muslim unless his Faith is based on strong convictions and his mind is clear from doubts.
Because Islam is complete only when it is based on strong convictions and freedom of choice, it cannot be forced upon anybody, for God will not accept this forced faith. Nor will He consider it a true Islam if it does not develop from within or originate from free and sound convictions. And because Islam insures freedom of belief many non-Muslim groups lived and still live in the Muslim countries enjoying full freedom of belief and conscience. The Muslims take this attitude because Islam forbids compulsion in religion. It is the light which must radiate from within, because freedom of choice is the cornerstone of responsibility. This does not exempt the parents from responsibility for their children. Nor does it condone their being indifferent to the spiritual welfare of their dependents. In fact, they must do everything possible to help them to build a strong inspiring faith.
