An-Nisaa 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 request from you a [legal] ruling. Say, "Allāh gives you a ruling concerning one having neither descendants nor ascendants [as heirs]." If a man dies, leaving no child but [only] a sister, she will have half of what he left. And he inherits from her if she [dies and] has no child. But if there are two sisters [or more], they will have two thirds of what he left. If there are both brothers and sisters, the male will have the share of two females.¹ Allāh makes clear to you [His law], lest you go astray. And Allāh is Knowing of all things.
