An-Nisa' 4:109

هَٰٓأَنتُمْ هَٰٓؤُلَآءِ جَٰدَلْتُمْ عَنْهُمْ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا فَمَن يُجَٰدِلُ ٱللَّهَ عَنْهُمْ يَوْمَ ٱلْقِيَٰمَةِ أَم مَّن يَكُونُ عَلَيْهِمْ وَكِيلًۭا

Ah! These are the sort of men on whose behalf ye may contend in this world; but who will contend with Allah on their behalf on the Day of Judgment, or who will carry their affairs through?
