Surah 16. An-Nahl, Ayah 77

As may be inferred from the sequence, the term ghayb - rendered here as the "hidden reality" - alludes in this context to the coming of the Last Hour, the time whereof is known to God alone (Zamakhshari). Parallel with this, it may also relate to God's Own existence, which cannot be directly established by the testimony of our senses (Baydawi) but, as the Qur'an consistently points out, may be inferred from the observable effects of His creativeness.

Lit., "the case [i.e., the manifestation] of the [Last] Hour will be like...", etc. - implying that it will be characterized by utter suddenness and unpredictability, both of them an outcome of the absence of any time-interval between God's decreeing it and its materialization: and this explains the phrase "or closer still" at the end of the above sentence.

This passage connects with the second sentence of verse {74} - "Verily, God knows [all], whereas you have no [real] knowledge."

The key to all things-not only those which we see and understand, but those which we do not see or of which we have no idea-is with Allah, Whose knowledge and power are supreme.

Lures of this world and its fleeting pleasures often make man forget that the life hereafter is an imminent reality. Many of those who claim to believe in the life to come act and behave as if it belonged to a distant future, and had no relevance to their present activities and mode of living. The Qur-An repeatedly reminds man that the Hour of Reckoning is not a distant possibility, but very close to man, and could come to pass any moment. The wisest course for man, therefore, is to be always alert and watchful and steer clear of all forms of sin and impiety, for when the Promised Hour comes it will come all of a sudden and without any prior notice.
