Musannaf Ibn Abi Shaybah 36951 — The words of Isa (peace be upon him)

Abu Thumamah said: The disciples (of Isa, peace be upon him) said: "O Isa (peace be upon him), what does it mean to make something purely for Allah Almighty?" He said: "It is that a man does a deed in a state where he would not like anyone among the people to praise him for it. The one devoted purely to Allah Almighty is he who fulfils the right of Allah Almighty before occupying himself with the rights of people, and gives the right of Allah Almighty preference over the right of people. When two tasks come before him, one for (the benefit of) this world and the other for (the benefit of) the Hereafter, he carries out the task for the Hereafter before the task for this world."
