Qur'an 4:109

هَـٰٓأَنتُمْ هَـٰٓؤُلَآءِ جَـٰدَلْتُمْ عَنْهُمْ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا فَمَن يُجَـٰدِلُ ٱللَّهَ عَنْهُمْ يَوْمَ ٱلْقِيَـٰمَةِ أَم مَّن يَكُونُ عَلَيْهِمْ وَكِيلًا

“Here you are - those who argue on their behalf in [this] worldly life - but who will argue with Allāh for them on the Day of Resurrection, or who will [then] be their representative?”
