It is narrated from Hazrat Ka'b bin Murrah (may Allah be pleased with him) that once I asked the Holy Prophet (peace and blessings be upon him), "At which part of the night is supplication most readily accepted?" The Holy Prophet (peace and blessings be upon him) replied, "In the last part of the night." And whoever frees a slave, Allah will free every limb of the one who frees from the Fire of Hell in exchange for every limb of the slave.

It is narrated from Hazrat Ka'b bin Murrah (may Allah be pleased with him) that once I asked the Holy Prophet (peace and blessings be upon him), "At which part of the night is supplication most accepted?" The Holy Prophet (peace and blessings be upon him) replied, "In the last part of the night, then prayers are accepted until the Fajr prayer. After the Fajr prayer, there is no prayer until the sun rises to the height of one or two spears, then prayers are accepted until the shadow becomes equal to one spear, then there is no prayer until the sun passes its zenith, then prayers are accepted until the sun becomes equal to one or two spears, then there is no prayer until sunset." And he said, "When you wash your face, the sins of the face are washed away; when you wash your hands, the sins of the hands are washed away; and when you wash your feet, the sins of the feet are washed away."
