An-Nisa 4:176 يستفتونك قل الله يفتيكم في الكلالة ان امرو هلك ليس له ولد وله اخت فلها نصف ما ترك وهو يرثها ان لم يكن لها ولد فان كانتا اثنتين فلهما الثلثان مما ترك وان كانوا اخوة رجالا ونساء فللذكر مثل حظ الانثيين يبين الله لكم ان تضلوا والله بكل شيء عليم ١٧٦

They seek a ruling from you. Say, “Allah gives you the ruling concerning Kalālah . If a person dies having no son, but he does have a sister, then, she will get one half of what he leaves. (On the other hand) He will inherit her if she has no child. If they are two (sisters), they will get two third of what he leaves. If they are brothers and sisters, both male and female, then, the male will get a share equal to that of two females.” Allah explains to you, lest you should go astray. Allah has full knowledge of everything.
