It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that my beloved friend (peace and blessings be upon him) advised me regarding three things and forbade me from three things. The advice was: (1) to perform Witr prayer before sleeping, (2) to fast three days in every month, (3) and to perform two units of Duha (forenoon) prayer. And the prohibitions were: looking around to the right and left during prayer, sitting like a monkey, and pecking like a rooster.
