Surah 10. Yunus, Ayah 19

Lit., "and then they disagreed [among themselves]". For an explanation of the term "one single community" (ummah wahidah), see surah {2}, note [197]. In the present context, this expression alludes not merely to mankind's one-time homogeneity, but also - by implication - to the fact, repeatedly stressed in the Qur'an (e.g., in 7:172 ), that the ability to realize God's existence, oneness and omnipotence is innate in man, and that all deviation from this basic perception is a consequence of the confusion brought about by man's progressive estrangement from his inborn instincts.

Lit., "it would indeed have been decided between them regarding all that they were differing in": i.e., had it not been for God's decree - which is the meaning, in this context, of the term kalimah (lit., "word") - that men should differ in their intellectual approach to the problems touched upon by divine revelation, "they would not have contended with one another after having received all evidence of the truth", but would all have held from the very outset, and would continue to hold, the same views (cf. 2:253 and the corresponding note [245]). Since, however, such a uniformity would have precluded men's intellectual, moral and social development, God has left it to their reason, aided by prophetic guidance, gradually to find their way to the truth. (See also surah {2}, note [198].) The above parenthetic passage must be read in conjunction with 2:213 .

 i.e., they split into believers and disbelievers.

 That He will delay their judgment until the Hereafter.

Cf. ii 213. All mankind was created one, and Allah's Message to mankind is in essence one, the Message of Unity and Truth. But as selfishness and egotism got hold of man, certain differences sprang up between individuals, races, and nations, and in His infinite Mercy He sent them messengers and messages to suit their varying mentality, to test them by His gifts, and stir them up to emulation in virtue and piety (v. 48).

Cf. vi. 115. ix 40, and iv. 171. "Word" is the Decree of Allah, the expression of His Universal Will or Wisdom in a particular case. When men began to diverge from one another (see last note), Allah made their very differences subserve the higher ends by increasing their emulation in virtue and piety, and thus pointing back to the ultimate Unity and Reality.
