It shall be no crime in the weak, nor in the sick, nor in those who do not find what they should spend (to stay behind), so long as they are sincere to Allah and His Messenger; there is no way (to blame) against the doers of good; and Allah is Forgiving, Merciful;

Say: As for him who remains in error, the Beneficent Allah will surely prolong his length of days, until they see what they were threatened with, either the punishment or the hour; then they shall know who is in more evil plight and weaker in forces
