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 ask thee for a pronouncement. Say: Allah hath pronounced for you concerning distant kindred. If a man die childless and he have a sister, hers is half the heritage, and he would have inherited from her had she died childless. And if there be two sisters, then theirs are two-thirds of the heritage, and if they be brethren, men and women, unto the male is the equivalent of the share of two females. Allah expoundeth unto you, so that ye err not. Allah is Knower of all things.
