Surah 10. Yunus, Ayah 5

Lit., "God has not created this otherwise than in accordance with truth" - i.e., to fulfil a definite purpose in consonance with His planning wisdom (Zamakhshari, Baghawi, Razi): implying that everything in the universe - whether existent or potential, concrete or abstract - is meaningful, and nothing is "accidental". Cf. 3:191 - "O our Sustainer! Thou has not created [aught of] this without meaning and purpose (batilan)"; and 38:27 - "We have not created heaven and earth and all that is between them without meaning and purpose, as is the surmise (zann) of those who are bent on denying the truth".

The nouns diya' and nur are often interchangeable, inasmuch as both denote "light"; but many philologists are of the opinion that the term diya' (or daw') has a more intensive connotation, and is used to describe "a light which subsists by itself, as that of the sun and fire" - that is, a source of light - while nur signifies "a light that subsists by some other thing" (Lane V, 1809, on the authority of Taj al-'Arus): in other words, light due to an extraneous source or - as in the case of the moon - reflected light.

The fitting epithet for the sun is dhiaa, "splendour and glory of brightness", and for the moon is "a light" (of beauty), the cool light that illuminates and helps in the darkness of the night. But the sun and moon also measure time. The simplest observation can keep pace with the true lunar months and lunar years, which are all that is required by a pastoral people. For agriculture solar years are required, as they indicate the changes of the seasons, but ordinary solar years are never exact; even the solar year of 365 1/4 days requires correction by advanced astronomical calculation.

Everything in Allah's creation has use and purpose, and fits into a Design. It is true in every sense of the word and it is good and just. It is not merely a matter of sport or freak (xxi. 16). Though so varied, it proclaims Allah's Unity; though a limited free-will is granted to creatures, the results of evil (which is rebellion) are neutralised and harmony is restored. Cf. iii. 191.
