And narrated to me Harun ibn 'Abdullah and Muhammad ibn Rafi', they said: narrated to us Ibn Abi Fudayk, from al-Dahhak ibn 'Uthman, from Ibrahim ibn 'Abdullah ibn Hunayn, from Abu Murrah, the freed slave of Umm Hani', from Abu al-Darda', who said: My beloved, peace and blessings be upon him, advised me with three things that I will never abandon as long as I live: fasting three days of every month, the Duha prayer, and not sleeping until I have prayed the Witr.
