Surah 10. Yunus, Ayah 100

I.e., by virtue of God's guidance and within the compass of what He has decreed to be man's nature, comprising the ability to discriminate between right and wrong. Since man's freedom of moral choice expresses itself in his willingness or unwillingness to conform to his true God-willed nature, it can be said to depend, in the last resort, on God's grace. (Cf. in this respect surah {2}, note [19], as well as surah {14}, note [4].)

Cf. 8:22 and {55}, as well as the corresponding note [58]. As in those verses, unbelief is here shown to be the result of a person's a-priori unwillingness to use his reason with a view to understanding God's messages, be they directly expressed in the revelations granted to His prophets, or - as the Qur'an once again stresses in the next verse - open to man's perception in the observable phenomena of His creation.

To creatures endued with Will, Faith comes out of an active use of that Will. But we must not be so arrogant as to suppose that that is enough. At best man is weak, and is in need of Allah's grace and help. If we sincerely wish to understand, He will help our Faith; but if not, our doubts and difficulties will only be increased. This follows as a necessary consequence, and in Quranic language all consequences are ascribed to Allah.

Rijs (from rajisa, yarjasu, or rajusa, yarjusu) has various meanings: e.g., (1) filth, impurity, uncleanness, abomination, as in ix. 95; (2) hence, filthy deeds, foul conduct, crime, abomination, thus shading off into (1), as in v. 90; (3) hence punishment for crime, penalty, as in vi. 125; (4) a form of such punishment, viz., doubt, obscurity, or unsettlement of mind, anger, indignation, as in ix. 125, and here, but perhaps the idea of punishment is also implied here.
