مُسْنَدُ أَحْمَدَ
Musnad Ahmad 3833
Musnad of Abdullah bin Mas'ood
It was narrated that ‘Abdullah (رضي الله عنه) said: I came to the Messenger of Allah (ﷺ) and said: O Messenger of Allah, Allah has caused Abu Jahl to be killed. He said: "Praise be to Allah Who has granted victory to His slave and caused His religion to prevail." On one occasion he - i.e. Umayyah - said: "... Who has fulfilled His promise to His slave and has caused His religion to prevail."
