In the statement: وَاللَّـهُ جَعَلَ لَكُم مِّن بُيُوتِكُمْ سَكَنًا (And Allah has made for you of your houses a place of comfort - 80), the word: بُيُوتِ (buyut) is the plural of bayt (بَیت) which means a house where night could be spent. Imam Al-Qurtubi says in his Tafsir:
کُلُّ مَا عَلَاکَ فَاَظَلَّکَ فَھُوَ سَقفُ وَّسَمَآُء وَ کُلُّ مَآ اَقَلَّکَ فَھُوَاَرضُ وَّ کُلُّ مَا سَتَرَکَ مِن جِھَاتِکَ الاَربَعِ فَھُوَ جِدَارُ فَاِذَا انتَظَمَت فَھُوَ بَیتُ
'Whatever is above your head and provides shade for you is roof or sky, and whatever holds you atop is earth, and whatever screens you out from all four sides are walls, and when (all these components are) put together properly, that is a house.
The real purpose of making a house is to have peace for body and heart
Here, by calling the human house a place of comfort and peace Allah Ta’ ala has made the logic and wisdom of making houses fully evident, that is, its real purpose is to have comfort of the body and peace of the heart. Customarily, the avenues of human work lie outside houses. Human work owes its existence to human movement and struggle. The real purpose of one's house is to go there, when tired after moving around and doing things, and rest and enjoy peace - even though, there are times when one keeps moving around and doing things in one's own house, but such instances are usually on the lower side.
This help us realize that peace is really the peace of mind and heart, something one finds in one's home only. This also tells us that the highest qualification of human home is that it provides peace. The world of today is at the height of its building craze. Limitless expenditure is incurred on their superficial finishing. But, there are very few homes among them which would provide peace of mind and heart. In fact, the artificially imposed additions in them become the very agents which destroy comfort and peace, and even in the absence of such material extravagance, the kind of people one confronts in the house is a misfortune which sucks that peace away. When such elegant houses are compared with a modest hut, the dweller of the hut who is blessed with comfort and peace for his body and heart is certainly living in a better place.
The Qur'an manifests the 'elan vital, the essence and the root of everything. Hence, peace was declared to be the real purpose of human home, and the greatest need indeed. Similarly, the real purpose of marital life was also determined to be peace as in: لِّتَسْكُنُوا إِلَيْهَا (so that you may enjoy peace with her - 30:21). A married life which fails to achieve this pur-pose remains deprived of the real benefit destined for it. Life in our day is infested with so many customs and formalities reaching the limits of absurdity in showing what you have through all sorts of artificial veneers. To compound the problem further, the outpourings of Western cultural and social norms and products have provided everything one needs to embellish personal surroundings with artificial decor - but, it has certainly made human beings become all deprived of what would be real comfort for their bodies and peace for their hearts.
The statement: مِّن جُلُودِ الْأَنْعَامِ (from the hides of the cattle - 80) and the statement: أَصْوَافِهَا وَأَوْبَارِهَا out of their wool and their fur and their hair 80) prove that it is Halal to use everything out of the hide, wool and hair of animals. Here, even the restriction that the animal be properly slaughtered or be a dead animal does not exist, nor is there any restriction as to their meat being Halal or Haram. It is perfectly Halal to use the hides of the animals of this kind by tanning them, and as for hair and wool, the death of the animal leaves just no effect on them. That remains halal and permissible without any specific technical treatment. This is the Madhab (creed) of the great Imam, Abu Hanifah. However, the hide of swine and all parts thereof are unclean and unfit for use under all conditions.
