Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh)) - كتاب التفسير
حدثنا أحمد بن يونس أراه قال حدثنا أبو بكر، عن أبي حصين، عن أبي الضحى، عن ابن عباس، {حسبنا الله ونعم الوكيل} قالها إبراهيم عليه السلام حين ألقي في النار، وقالها محمد صلى الله عليه وسلم حين قالوا {إن الناس قد جمعوا لكم فاخشوهم فزادهم إيمانا وقالوا حسبنا الله ونعم الوكيل}
Narrated Ibn `Abbas: 'Allah is Sufficient for us and He Is the Best Disposer of affairs," was said by Abraham when he was thrown into the fire; and it was said by Muhammad when they (i.e. hypocrites) said, "A great army is gathering against you, therefore, fear them," but it only increased their faith and they said: "Allah is Sufficient for us, and He is the Best Disposer (of affairs, for us)." (3.173)
