These verses were sent down to console and strengthen our prophet, and the believers who had repented with him. They were also instructed to fear not the large number of enemies, and to stand firm in front of them; that God would help and support them in time:ِ
      ``Be not then in doubt concerning what these people worship.''

      Their worship was not based on study and knowledge. They merely imitated their fathers, and their creed was not a religion, but some sort of a culture they imitated from one another. They rejected the Message of God and denied the prophets and went on their own way of evil and perversion, and so said Allah to them:ِ

      ``Soon shall we give them their share of torment which is the natural effect of their own deeds. We shall repay them their wrongs and oppressions, in full and undiminished.''

      And once again to comfort his prophet, Allah, says:ِ

      ``O, prophet! It is not only your people who have fallen in variance concerning you and your Book.'' So was the case with the people of Moses tooِthe Israelites:ِ ``And we also gave Moses the Book, but differences arose therein. And had it not been for a word that preceded from your Lord, it would have been judged between them.''

      In other word; if We do not hasten to punish your people, we deem that more advisable; because it might be that some of them in future repent and turn to good purposes.

      ``So be you , o, Mohammad steadfast, and continue your undertakings with perseveranceِyou and those who have repented with you; and do not transgress....''

      This verse (NO.112) was the hardest of all the verses that were sent down to our prophet (AS). So when he was asked:ِ ``Why did your hairs grow grey so soon?'' He answered:ِ ``The chapter of Hood turned me old! And he referred to the said verse, which is sometimes called the verse of patience and perseverance.''

      Patience and perseverance which imply a holding fast to a purpose, aim, or to a course of actions; is considered among the most important means and principles of any success. There is a Persian proverb saying:ِ ``Patience is bitter but bears sweet fruit.'' William Shakspeare too, in his Othello has :ِ ``How poor are they, that have no patience,

      ``What wound did ever heal, but by degree?''

      So, if Mohammad's patience and perseverance whitened his black hairs, it also led to his extraordinary success, and this was for the said verse of Hood which told him to attempt the end and never stand in doubt:

      There are four important instructions to be accomplished in the said verse. These are as follows:ِ

      1ِ To stand firm and resolute, and to follow the object with perseverance, giving no way to feebleness.

      2ِ Work hard and do it only for the sake of Allah your Lord.
      3ِ Encourage your followers to be steadfast too, with you.
      4ِ Do not transgress and keep within due bounds observing reasonable limits.

      The above four instructions have a general application on all men, and on all ages, and are not peculiar to Mohammad's life time, and his disciple.
