Read and reflect on verse 526 from Surah An-Nisaa: And unto everyone have We appointed heirs to what he may leave behind: parents, and near kinsfolk, and those to whom you have pledged your troth give ...
وَلِكُلٍّ جَعَلْنَا مَوَالِيَ مِمَّا تَرَكَ الْوَالِدَانِ وَالْأَقْرَبُونَ ۚ وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ فَآتُوهُمْ نَصِيبَهُمْ ۚ إِنَّ اللَّهَ كَانَ عَلَىٰ كُلِّ شَيْءٍ شَهِيدًا
And unto everyone have We appointed heirs to what he may leave behind: parents, and near kinsfolk, and those to whom you have pledged your troth give them, therefore, their share. Behold, God is indeed a witness unto everything.
