Musnad Ahmad 31:733

And with this chain of narration, that the Messenger of Allah, peace and blessings of Allah be upon him, said: "Whoever humbles himself one degree for the sake of Allah, Allah will raise him one degree, until He places him in the highest heights (Illiyyun). And whoever acts arrogantly one degree against Allah, Allah will lower him one degree, until He places him in the lowest of the low (Asfal al-Safilin)."
