Commentary:
We learn from this Hadith that to withhold guidance in the matter of religion from anybody who seeks it, is a grave sin which is threatened with Hell. Unfortunately, the religious scholars who are shackled in religious prejudices and terribly lack interest in juristic matters have developed a habit of concealing religious knowledge from people. In fact, this grave sin has become so alarming that any further delay to eradicate it will prove ruinous for us. May Allah grant us true guidance.
