أَمْ تُرِيدُونَ أَن تَسْأَلُوا رَسُولَكُمْ كَمَا سُئِلَ مُوسَىٰ مِن قَبْلُ ۗ وَمَن يَتَبَدَّلِ الْكُفْرَ بِالْإِيمَانِ فَقَدْ ضَلَّ سَوَاءَ السَّبِيلِ (108)
(2:108) Would you then ask your Prophet such questions as were asked of Moses in former times? *110 In fact, anyone, who changes the way of belief for that of disbelief, has surely swerved from the Right way.
*110). The Jews, who were addicted to hair-splitting arguments, instigated the Muslims to ask the Prophet a great many questions. God, therefore, cautioned the Muslims against following the example of the Jews in this matter, and admonished them against unnecessary inquisitiveness. The Prophet himself often warned the Muslims that excessive inquisitiveness (which was devoid of religious earnestness and the sincere desire to do God's will) had been the ruin of earlier religious communities. (Muslim, 'Faddil', 130; Bukhari, '1'tisim', 2 - Ed.) He stressed that people need not delve too deeply into questions left unelucidated by God or His Messenger. It was better to follow the injunctions which were clearly laid down, abstain from things prohibited, and avoid excessive inquiry about far-fetched, hypothetical issues, attending instead to questions of practical significance.
