Musnad Ahmad 4100

It was narrated that Sulaiman said: I heard Zaid bin Wahb say: I heard 'Abdullah bin Mas'ood narrate from The Prophet (ﷺ): "After I am gone you will see selfishness, turmoils and things that you disapprove of.” We said: O Messenger of Allah, what do you instruct us to do, if any of us live to see that? He said: “Pay your dues (to others), and ask Allah for what is due to you.”
