If an individual ignores worldly rights and obligations and does not fulfil his responsibility towards his wife and children, nor occupies himself in efforts to earn a livelihood, but all the time stays in meditation, he ruins his life and does not fulfil the purpose of living. If this were Allah's aim, what would have the need for creating and populating the world when there was already a category of creatures who were all the time engaged in worshipping and adoration.
Nature has made man to stand on the cross-roads at which the midway is the centre of guidance. If he deviates from this point of moderateness even a bit, this way or that way, there is shear misguidance for him.
That midway is that he should neither bend towards this world to such an extent as to ignore the next life, devoting himself entirely to this one, nor should he abstain from this world so as not to have any connection with anything of it, confining himself to some corner leaving everything else. Since Allah has created man in this world he should follow the code of life for living in this world, and should partake of the comforts and pleasures bestowed by Allah within moderate limits.
The eating and using of things made lawful by Allah is not against Allah's worship, but rather Allah has created these things for the very purpose that they should be taken advantage of. That is why those who were the chosen of Allah lived in this world with others and ate and drank like others. They did not feel the need to turn their faces away from the people of the world, and to adopt the wilderness or the caves of mountains as their abodes, or to live in distant spots.
On the other hand they remembered Allah, remained disentangled from worldly affairs, and did not forget death despite the pleasures and comforts of life.
The life of asceticism sometimes produces such evils as ruin the next life also as well as this one, and such an individual proves to be the true picture of "the looser in this life as well as the next." When natural impulses are not satisfied in the lawful and legal way the mind turns into a centre of evil-ideas and becomes incapable of performing worship with peace and concentration; and sometimes passions so overcome the ascetic that breaking all moral fetters, he devotes himself completely to their satisfaction and consequently falls in an abyss of ruin for which it is impossible to extract himself.
