Surah 13. Ar-Ra'd, Ayah 4

I.e., regarding the nature of the soil, fertility and kind of vegetation. The necessity of this interpolation - which, in the consensus of all commentators, conveys the meaning of the above phrase - becomes apparent from the subsequent clauses.

Lit., "non-clustered" (ghayr sinwan) - i.e., each tree having separate roots.

Cf. 6:99 and {141}, where a similar stress is laid on the multiformity of plants - and their varying beneficence to man and animal - as some of the signs of God's purposeful, creative activity.

Does "growing out of single roots or otherwise" qualify "palm trees" or "vines" and "corn" as well? The former construction is adopted by the classical Commentators: in which case the reference is to the fact either that two or more palm trees occasionally grow out of a single root, or that palm trees grow sometimes as odd trees and sometimes in great thick clusters. If the latter construction is adopted, the reference would be to the fact that date-palm (and palms generally) and some other plants arise out of a single tap-root, while the majority of trees arise out of a net-work of roots that spread out extensively. Here is adaptation to soil and water conditions,-another Sign or wonder of Creation.

The date-palm, the crops of food-grains, and the grape-vine are all fed by the same kind of water, yet how different the harvests which they yield! And that applies to all vegetation. The fruit or eatable produce may vary in shape, size, colour, flavour, etc., in endless variety.
