This law includes illegitimate children...

This law includes illegitimate children, because to kill an illegitimate child is the same as killing any other Muslim individual. It is obligatory upon the testamentary guardians of fathers and grandfathers to undertake the guardianship and supervision of their immature or mentally disabled children and their properties in the event that their guardian dies and entrusts this responsibility to the testamentary guardian.

When fathers, grandfathers, or testamentary guardians are absent and when the supreme religious authority cannot be reached, it is obligatory upon any believer ( mu’min )—if a just[^1] ( ‘adil ) believer is not available—to look after and supervise orphans and the mentally disabled and provide for them through these individuals’ own property. Naturally, relatives have priority in this regard.

It is obligatory upon solvent fathers and paternal grandfathers to pay the marriage expenses of their male and female children and grandchildren when they are in need for marriage, too destitute to afford their own marriages, and expected to commit sins otherwise.

As to children and grandchildren, it is obligatory upon them to pay the marriage expenses of their single fathers and mothers according to the aforementioned conditions, since it is obligatory upon them to supply their parents with the necessary provisions. However, this issue is controversial.

It is obligatory for a man who marries an immature girl by the permission of her legal guardian and copulates with her before she attains maturity, causing her urinary and vaginal canals or vaginal and anal canals to become joined, to pay her life-time alimony even if she divorces him and marries another man.[^2] In the aforementioned case, it is perpetually forbidden for the husband to copulate with the wife even if he does not intend to divorce her.[^3] It is obligatory upon wives whose husbands apostatize to separate from them and observe a widow’s period of waiting[^4] ( ‘iddah ).

The period of waiting starts from the time of the husband’s apostasy, regardless of whether he repents or not. Before entering into a marriage contact, it is obligatory for men who suffer one of the following four defects to declare so: (1) insanity, although periodical, (2) having defected testicles or lack thereof, (3) having no genital organ, and (4) impotency (i.e. inability to have sexual intercourse).
