Translation of the verse 37 from Surah Al-Qasas : Number of verses 88 - - page 390 - Part 20.
Musa (Moses) said: "My Lord knows best him who came with guidance from Him, and whose will be the happy end in the Hereafter. Verily, the Zalimun (wrong-doers, polytheists and disbelievers in the Oneness of Allah) will not be successful."
And Moses said, "My Lord is more knowing [than we or you] of who has come with guidance from Him and to whom will be succession in the home. Indeed, wrongdoers do not succeed."
(28:37) Moses replied, "My Lard is fully aware of the person who has brought guidance from Him and He alone knows who will fare best in the end; the truth is that the unjust never attain true success. " *51
*51) That is, "You think I am a magician and a forger, but my Lord is well aware of me. He knows what sort of a man is the person whom He has appointed as a Messenger; and the final judgement rests with Him. If I am a liar, I shall meet an evil end; and if you are a liar, you should know that your end will not be good. In any case, the inevitable fact is that the unjust will not attain true success. He who is not Allah's messenger but falsely presents himself as a messenger for selfish motives, is also unjust and will not attain success. And the one who rejects a true Messenger by false accusations and suppresses the Truth by deceit and fraud, is also unjust and will never attain success."
