Musnad Ahmad 30:564

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Ayyub, from Ibn Sirin, from Abu Hurayrah, from the Prophet (peace and blessings of Allah be upon him), who said: "None of you should revile Time (ad-dahr), for indeed Allah is Time. And none of you should say to the grape: 'al-karm' (the noble/generous), for indeed 'al-karm' is the Muslim man."
