On the ground of fosterage, a Muslim marriage is:

Fosterage in this terminology means the legally prohibited milk relationship created by nursing, not merely being raised by an unrelated foster family. It creates a permanent marriage prohibition in the classical rule, so a marriage within that prohibited relationship is batil, or void. A temporary impediment instead may create an irregular marriage; muta is a different category and does not remove the prohibition.

Current law: The classical milk-relationship rule must be distinguished from ordinary fostering or adoption. Covered Uttarakhand marriages now require a separate UCC assessment: section 4(iv) contains its scheduled relationship rule and section 4(v) also bars marriages prohibited by another law in force. This note does not assume that the Code abolished every existing milk-kinship prohibition.
