It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) used to encourage standing (in prayer) during Ramadan, but did not give a firm command, and used to say: Whoever stands (in prayer) during Ramadan with faith and seeking reward, all his past sins will be forgiven. And the Noble Prophet (peace and blessings be upon him) did not gather the people for standing (in prayer).
