'We provide them every day from our remnant… and no one from among them returns to us.'

"And when you do not bring them a sign, they say, 'Why have you not contrived it?'" meaning: Why did you not bring it from yourself? Allah said: "Say," to them, O Muhammad: "'I only follow what is revealed to me from my Lord. This is insight,'" meaning: the Qur'an.

Muhammad said: The singular of 'basa'ir' (insights) is 'basira'; it is a word that functions in various ways, and its root is the clarity and manifestation of a thing.
