Al-Mumtahana 60:3
لَن تَنفَعَكُمْ أَرْحَامُكُمْ وَلَآ أَوْلَـٰدُكُمْ ۚ يَوْمَ ٱلْقِيَـٰمَةِ يَفْصِلُ بَيْنَكُمْ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
Neither your womb-relations nor your children will benefit you on the Day of Judgment. He will decide between you, and Allah is watchful of what you do.
