48:18
INDEED, well-pleased was God with the believers when they pledged their allegiance unto thee [O Muhammad] under that tree, 21 for He knew what was in their hearts; and so He
bestowed inner peace upon them from on high, and rewarded them with [the glad tiding of] a victory soon to come, 22 (48: 19) and [of] many war-gains which they would achieve: for God is indeed almighty, wise.
[[Asad’s note - 21 I.e., at Hudaybiyyah (see introductory note).
22 Most of the commentators assume that this relates to the conquest of Khaybar, which took place a few months after the Truce of Hudaybiyyah. It is probable, however, that the implication is much wider than that - namely, a prophecy of the almost bloodless conquest of Mecca in the year 8 H., the victorious establishment of Islam in all of Arabia and, finally, the tremendous expansion of the Islamic Commonwealth under the Prophet's immediate successors. ]]
