Surah 25. Al-Furqan, Ayah 33

Lit., "come to thee with a parable (mathal)" - i.e., with all manner of seemingly plausible parabolic objections (exemplified in verses {7-8}, {21} and {32} of this surah as well as in many other places in the Qur'an) meant to throw doubt on Muhammad's claim to prophethood and, hence, on the God-inspired character of the Qur'anic message.

Sc., "of the problem or problems involved": an allusion to the self-explanatory character of the Qur'an. Throughout this section (verses {30-34}) the personal pronoun "thou" (in the forms "thy" and "thee") relates not only to the Prophet but also to every one of his followers at all times.

Divine knowledge is a fathomless ocean. But glimpses of it can be obtained by any individuals sincerely searching for the Truth. Their progress will be in grades. If they ask questions, and answers are then furnished to them, they are more likely to apprehend the Truth, as they have already explored the part of the territory in which they are interested. In the same way, when concrete questions arise by the logic of events, and they are answered not only for the occasion, but from a general stand-point, the teaching has a far greater chance of penetrating the human intelligence and taking shape in practical conduct. And this is the usual way of instruction in the Qur-an.
