..." Noah(a.s.)added telling them if they were able, they should go ahead and put an end to his life, and not spare him a single moment. Here is his statement: "... Then make decision on me, and give me no respite. '" It has been narrated that before noon on the Day of Ashura Imam Hussein(a. s.)also recited this very verse to the Kufan army.
This is a lesson for all Islamic leaders who might feel daunted when confronted by a multitude of enemies, rather; they must, by taking recourse to Allah and appealing to Him, with utmost decisiveness challenge them and humiliate them their power which would reinforce the morale of their followers and lower that of their enemies.
In the foregoing verse, the issue in question centers on the conspiracy of their enemies with regard to the lives of the prophets. The issue dealt with in this verse relates to the prophets' lack of expectations for reward and wealth from the side of people. Noah(a.s.)in this verse announced that if the unbelievers were to turn away from the truth, not accepting or following it, he did not expect any rewards for bringing them the message.
This was his mission, so they should not balk at acceptance for fear of feeling that they would end up owing him something, which would be burdensome to them.
The verse says: " But if you turn back, I have not asked you for any recompense, my recompense is only upon Allah, ..." The verse also implies that if they turn away from accepting his words, he would not be at a disadvantage for he was not after their wealth(he did not covet)so that their turning away would put him at a loss, on the contrary, their rejection would turn out to be at their own disadvantage.
He emphasized that his reward for the prophetic mission and its accomplishment lay with Allah alone. And Allah, the Gracious, had commissioned Noah(a.s.)to be among those who had submitted themselves to His commandments for, indeed, the best of what the servants of Allah can practice is to obey and submit to Him. The verse continues as follows: "... and I am commanded to be of those(who)surrender(unto Him).
