It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that I have been advised regarding three things which I will never abandon whether I am traveling or at home: (1) to perform the Witr prayer before sleeping, (2) to fast three days in every month, (3) to offer two rak'ahs of Duha (forenoon) prayer. Later, Hasan began to mention "the Friday bath" in its place.
