Hijaab of Body to put outer garments when going out:
O Prophet! Tell thy wives and daughters, and the believing women, that they should cast their outer garments over their body (when abroad): that is most convenient, that they should be known (as such) and not molested. And Allah is Oft-Forgiving, Most Merciful. (Al_Quraan_033.059)
Relatives and Friends need each other:
O ye who believe! let those whom your right hands possess, and the (children) among you who have not come of age ask your permission (before they come to your presence), on three occasions:
before morning prayer; the while ye doff your clothes for the noonday heat; and after the late-night prayer: these are your three times of undress: outside those times it is not wrong for you or for them to move about attending to each other: Thus does Allah make clear the Signs to you: for Allah is full of knowledge and wisdom. And when the children among you have attained to puberty, let them seek permission as those before them sought permission; thus does Allah make clear to you His communications, and Allah is knowing, Wise. And (as for) women advanced in years who do not hope for a marriage, it is no sin for them if they put off their clothes without displaying their ornaments; and if they restrain themselves it is better for them; and Allah is Hearing, Knowing.
There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together (including JOINTFAMILY- SYSTEM which may help saving lots of expenditure) or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand. (Al_Quraan_024:061)
Remember: Build your Sweet Home to not only smell good but also taste sweet as well, which can only be done through positive attitudes. A father would never like to see his sons living separately in his life, and prefer to live in a joint-family-system along with his grand children, if all can afford with positive attitudes. A JOINT-FAMILY-SYSTEM may help save lots of expenditures, if you all have
positive attitudes. Wish you all the best. AMEEN.
