Sahih International:
And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave, after any bequest they [may have] made or debt. And for them [i.e., the wives] is one fourth if you leave no child. But if you leave a child, then for them is an eighth of what you leave, after any bequest you [may have] made or debt. And if a man or woman leaves neither ascendants nor descendants but has a brother or a sister, then for each one of them is a sixth. But if they are more than two, they share a third, after any bequest which was made or debt, as long as there is no detriment [caused]. [This is] an ordinance from Allah, and Allah is Knowing and Forbearing. (An-Nisa [4] : 12)
1 Mufti Taqi Usmani
For you there is one-half of what your wives leave behind, in case they have no child. But, if they have a child, you get one-fourth of what they leave, after (settling) the will they might have made, or a debt. For them (the wives) there is one-fourth of what you leave behind, in case you have no child. But, if you have a child, they get one eighth of what you leave, after (settling) the will you might have made, or a debt. And if a man or a woman is Kalālah (i.e. has neither parents alive, nor children) and has a brother or a sister, then each one of them will get one-sixth. However, if they are more than that, they will be sharers in one-third, after (settling) the will that might have been made, or a debt, provided that the will must not be intended to harm anyone. This is a direction from Allah. Allah is All-Knowing, Forbearing.
