An-Nisa 4:109

Haantum haola-i jadaltumAAanhum fee alhayati addunya famanyujadilu Allaha AAanhum yawma alqiyamati amman yakoonu AAalayhim wakeela

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?

Look, this is what you are! You have argued for them in the worldly life, but who shall argue for them with Allah on the Day of Judgement, or who shall be their defender?
