English Translation of Hadith
Hazrat Abdullah bin Abbas (May Allah be pleased with him) said "When (Prophet) Ibrahim PBUH (Abraham) was thrown into the fire, he said: "Allah (Alone) is sufficient for us, and, He is the Best Disposer of affairs.” So did Messenger of Allah Muhammad 
[SAWW](PBUH) when he was told: "A great army of the pagans had gathered against him, so fear them". But this (warning) only increased him and the Muslims in Faith and they said: "Allah (Alone) is sufficient for us, and He is the Best Disposer of affairs (for us)".
