Surah Baqara, Aya 26
ndeed, Allah does not disdain to propound a parable of a gnat, or of something [even] less than that. Now, as for those who have attained to faith, they know that it is the truth from their Sustainer, whereas those who are bent on denying the truth say, "What could Allah mean by this parable?" In this way does He cause many to go astray, just as He guides many, but none does He cause thereby to go astray save the iniquitous (fasiqin).
Questions:
What are Qur'anic parables? What do they do?
What is a ba`uda?
Why a gnat is mentioned in the Book of Allah Most High?
