Overall meaning : Allah Almighty mentions that that Noah, peace be upon him, called out to Him, saying, 'Lord, You promised you would save me and my family from drowning and destruction, and this son of mine is of my family. Your promise is surely true and is always fulfilled, and You are the Most Just of all judges.’
'Noah,’ Allah said, 'your son who perished is not of your believing family members whom I promised you to save, for he was guilty of unbelief, which is an evil deed. Do not, therefore, ask Me for something about which you have no knowledge. I admonish you, lest you should be among the ignorant by asking me for such a thing.’
'I seek refuge in You, Lord from asking You for anything about which I have no knowledge,’ Noah said. 'Unless You forgive me and have mercy on me, I will surely be among the losers.’
'Disembark, Noah in peace and security from Us,’ Allah said, 'and with Our blessings on you as well as on many nations that will descend from the believers who are with you in the Ark. But as for other nations from their unbelieving descendants, We will provide for them to enjoy themselves until their appointed time of death, then We will make them suffer a painful punishment on the Day of Judgement.’
The story of Noah and his people We have related to you, Muhammad, is one of the true accounts of the distant, unknown past, which We reveal to you. Neither you nor your people knew it before this time. Therefore, persevere and exercise patience, when your people disbelieve you do harm to you, as did the prophets before you, for the best end result in this life and in the life to come is for the God-fearing who do what Allah commands and avoid what He forbids.
