O you who believe! seek assistance through patience and prayer; surely Allah is with the patient ones (153).
And do not speak of those who are slain in Allah’s way as dead; nay, (they are) alive, but you do not perceive (154).
And We will most certainly try you with somewhat of fear and hunger and loss of property and lives and fruits; and give good news to the patient ones (155),
who, when a misfortune befalls them, say: “Surely we are Allah’s and to Him we shall surely return” (156).
Those are they on whom are blessings and mercy from their Lord, and those are the followers of the right course (157).
A single theme joins the five verses like a pearl-string; the sentences form a sequence and the topic is developed harmoniously; the beginning leads to the end, and the points to the beginning. It shows that they were revealed together, not separately.
The context indicates that they must have been revealed shortly before the law of al-jihad اَلجِهَادُ ) = war in the way of Allah) was promulgated and the Muslims were ordered to fight in the cause of religion.
The verses prepare the believers for some trials which they will have to undergo, some misfortunes which will befall them. Not the usual type of trial and hardship, but some extraordinary misfortunes which will afflict the whole community and will continue, recurring every now and then.
Man, like any other creature in this world, always faces some hardships and troubles which disturb and disrupt the pattern of his personal life.
Death, sickness, fear, hunger, grief, poverty and deprivation are but a few examples of such personal misfortunes. It is the course which Allah has laid down for His servants. This world is a place of struggle and competition; the life is a chain of never-ending changes and transformations.
And you shall not find any alteration in the course of Allah; and you shall not find any change in the course of Allah (35:43).
