And when Allah, the Most High, invalidated their faces of objection against the Messenger and the one sent from the perspective of their ignorance once, and from the perspective of their claim of invalidity another time, He alerted them to another aspect that they are the most knowledgeable of people regarding its invalidity, to establish the claim of its truth when the faces of the objections are removed. He said, denying: ﴿Or do you ask them﴾ meaning about what you have brought them ﴿as a payment﴾. Al-Baghawi said: as a reward and compensation. Ibn Maktum said in combining between the ambiguous and the definitive: and the kharj and the kharaj is something that the people give out in the year from their wealth in a known amount, and the kharaj is the produce of the servant and the maid. Al-Zajjaj said: the kharaj is the spoils, and the kharj is the tax and the jizyah. Al-Asbahani said: Abu Amr ibn al-Ala was asked and he said: the kharaj is what is obligatory upon you and must be paid, and the kharj is what you voluntarily give without obligation.

And when denial means negation, the position of the causative fa in His saying: ﴿So the kharj﴾ is appropriate, meaning: Or do you ask them that so your question becomes a cause for your accusation and not asking, because the kharj of ﴿your Lord﴾ whom you have never intended other than Him at any time ﴿is better﴾ than their kharj, because His kharj is not cut off nor prevented from any of His wrongdoer servants, so how about the good-doers! And as if He named it kharj indicating that He has made the sustenance of everyone obligatory upon themselves by a promise that there is no failure in it ﴿and He is the best of providers﴾ for He knows what is good for every sustenance and what corrupts it, so He gives it according to what He knows of it and does not make him in need of a question.
