1-50 Al-Hussein ibn Ahmad ibn Idris - may God be pleased with him - narrated that his father quoted on the authority of Muhammad ibn Ahmad, on the authority of Ahmad ibn Muhammad, on the authority of Some of the Al-Nofelites and Mohammad ibn Sin’an who linked it up to the Commander of the Faithful Imam Ali (MGB) who said,

“Pay more attention to the acceptance of your deeds than the deeds themselves. Abstinence in the world is reducing aspirations. And gratitude for all blessings is avoiding everything which God the Honorable the Exalted has forbidden. Whoever strains his body has pleased his Lord, and whoever doesn’t strain his body has disobeyed his Lord.”
