Musannaf Ibn Abi Shayba 33:607

Ghundar narrated to us, from Shu'bah, from Sa'd ibn Ibrahim, from his father, from his grandfather Abd al-Rahman ibn Awf, that food was brought to him. Abd al-Rahman said: "Hamza was killed and he did not find anything to be shrouded in, and he is better than me. And Mus'ab ibn Umayr was killed and he is better than me, and he did not find anything to be shrouded in. And we have been granted of it [worldly wealth] what we have been granted." Then Abd al-Rahman said: "I fear that our good things have been hastened for us in the worldly life."
