An-Nisa 4:12 ۞ ولكم نصف ما ترك ازواجكم ان لم يكن لهن ولد فان كان لهن ولد فلكم الربع مما تركن من بعد وصية يوصين بها او دين ولهن الربع مما تركتم ان لم يكن لكم ولد فان كان لكم ولد فلهن الثمن مما تركتم من بعد وصية توصون بها او دين وان كان رجل يورث كلالة او امراة وله اخ او اخت فلكل واحد منهما السدس فان كانوا اكثر من ذالك فهم شركاء في الثلث من بعد وصية يوصى بها او دين غير مضار وصية من الله والله عليم حليم ١٢

And unto you belongeth a half of that which your wives leave, if they have no child; but if they have a child then unto you the fourth of that which they leave, after any legacy they may have bequeathed, or debt (they may have contracted, hath been paid). And unto them belongeth the fourth of that which ye leave if ye have no child, but if ye have a child then the eighth of that which ye leave, after any legacy ye may have bequeathed, or debt (ye may have contracted, hath been paid). And if a man or a woman have a distant heir (having left neither parent nor child), and he (or she) have a brother or a sister (only on the mother's side) then to each of them twain (the brother and the sister) the sixth, and if they be more than two, then they shall be sharers in the third, after any legacy that may have been bequeathed or debt (contracted) not injuring (the heirs by willing away more than a third of the heritage) hath been paid. A commandment from Allah. Allah is Knower, Indulgent.

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,¹ after any bequest which was made or debt, as long as there is no detriment [caused].² [This is] an ordinance from Allāh, and Allāh is Knowing and Forbearing.

In what your wives leave, your share is a half, if they leave no child; but if they leave a child, ye get a fourth; after payment of legacies and debts. In what ye leave, their share is a fourth, if ye leave no child; but if ye leave a child, they get an eighth; after payment of legacies and debts. If the man or woman whose inheritance is in question, has left neither ascendants nor descendants, but has left a brother or a sister, each one of the two gets a sixth; but if more than two, they share in a third; after payment of legacies and debts; so that no loss is caused (to any one). Thus is it ordained by Allah; and Allah is All-knowing, Most Forbearing.
