Abu Ja’far (asws) having said: ‘The Law (Sharia) of Noah (as) was that they should worship Allah (azwj) with Oneness (Al-Tauheed), and have sincerity, and not associate others, ‘وَ هِيَ الْفِطْرَةُ الَّتِي فَطَرَ النَّاسَ’ and this is the natured upon which the people have been Created. And Allah (azwj) Took a Covenant with Noah (as) and to All the Prophets (as) that they (as) would worship Allah (azwj) and will not associate anything with Him (azwj), and Commanded for the Salat, and the enjoining of the good, and the prohibiting of the bad, and the Permissibles, and the Prohibitions, and did not Necessitate upon them the rules of the Limits, nor about the necessary inheritance. So this is the Law which Noah (as) remained upon among them for a thousand years except for fifty years (950) calling them secretly and in the open. So when they refused and rebelled, he (as) said to his (as) Lord (azwj): ‘I (as) have been overcome, so Help!’ So Allah (azwj) Revealed unto him (as): “No one else from your (as) people are going to believe except for the ones who have already believed, so do not be disheartened at what they have done”. So for that reason Noah (as) said: ‘They will not give birth to anyone except tyrannous infidels’. So Allah (azwj) Revealed unto him (as) to make the ship’.
