Once Saʿd (bin Abi Waqqas) thought that he was superior to those who were below him in rank. On that the Prophet ﷺ said, "You gain no victory or livelihood except through (the blessings and invocations of) the poor amongst you."

النَّبِيُّ ﷺ هَلْ تُنْصَرُونَ وَتُرْزَقُونَ إِلاَّ بِضُعَفَائِكُمْ

'Is there anyone amongst you who has enjoyed the company of the companions of the Prophet?' It will be said, 'Yes,' and they will be given victory (by Allah).
