'And Ibn Abbas (may Allah be pleased with them both) narrated that Abu Sufyan (may Allah be pleased with him) informed me that Caesar (the king of Rome) said to me: I asked you whether the noble people have followed him (the Prophet, peace and blessings be upon him) or the weak and poor ones? You replied that the weak and poor ones have followed him, and it is this group that are the followers of the Prophets.'

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