Sayyidina Ibrahim (peace be upon him)

Narrated Hadrat Ibn 'Abbas (may Allah be pleased with him): 'Allah is Sufficient for us and He is the best Disposer of affairs," was said by Sayyidina Ibraham (peace be upon him) when he was thrown into the fire; and it was said by Sayyidina Muhammad (may Allah's blessings and peace be upon him) 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) (Bukhari)
