O You (Prophet) the great selector of companions, the best caravan leader!

Stay vigilant even by night, and never fall short on it - [As Head of the State the Prophet is responsible for arranging peace and security for all citizens (17:79, 76:26). 'Illa' here, as in many other verses, represents 'never', and not 'except' (11:107-108, 55:33, 87:6-7). 'Al-Manar' vol 1 Pg 414]

Half of it, or a little less.

Or, you shall increase it whenever warranted. And convey the Qur'an in a calm distinctive manner, stage by stage.

We are charging you with a substantial declaration (a lofty mission).

The vigil of the night impresses the minds most strongly, and the speech is most upright. [Mutual consultation with companions is better done in the silence of night]

By day you are engaged in continued strife.

Keep eminent the Name of your Lord and detach yourself from needless pursuits for His sake.

Lord of the East and the West! There is no god but He. So, hold on to Him as Dispenser of affairs.

Endure with patience whatever people may say, and leave them graciously. [5:13, 15:85]
