Abdullah bin Abbas reported,

"Those to whom people said, 'The people have gathered against you, so fear them,' but it only increased them in faith, and they said, 'Allah is sufficient for us, and He is the best disposer of affairs'" [Al Imran 3:173]. Ibrahim said these words when he was cast into the fire, and Muhammad ﷺ said them when they told him, "The people have gathered against you, so fear them," but it only increased them in faith, and they said, "Allah is sufficient for us, and He is the best disposer of affairs."

عن ابن عباس

{الذين قال لهم الناس إن الناس قد جمعوا لكم فأخشوهم فزادهم إيمنا وقالوا حسبنا الله ونعم الوكيل}[آل عمران: ١٧٣]، قالها إبراهيم عليه السلام حين ألقى فى النار، وقالها محمد ﷺ حين قالوا: {إن الناس قد جمعوا لكم فأخشوهم فزادهم إيمانا وقالوا حسبنا الله ونعم الوكيل}
