(41) The revelation of the Book (this Qur'an) in which there is no doubt is from the Lord of the 'Alamin (mankind, jinn and all that exists)!

(42) "Salam (peace) be upon Nuh (Noah) (from Us) among the 'Alamin (mankind, jinn and all that exists)!"

(43) "Then what think you about the Lord of the 'Alamin (mankind, jinn, and all that exists)?"

(44) And all the praises and thanks be to Allah, Lord of the 'Alamin (mankind, jinn and all that exists).

(45) Say (O Muhammad صلى الله عليه وسلم): "No wage do I ask of you for this (the Qur'an), nor am I one of the Mutakallifun (those who pretend and fabricate things which do not exist).

(46) And you will see the angels surrounding the Throne (of Allah) from all round, glorifying the praises of their Lord (Allah). And they (all the creatures) will be judged with truth. And it will be said, "All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists)."

(47) Allah, it is He Who has made for you the earth as a dwelling place and the sky as a canopy, and has given you shape and made your shapes good (looking) and has provided you with good things.

(48) He is the Ever Living, La ilaha illa Huwa (none has the right to be worshipped but He); so invoke Him making your worship pure for Him Alone (by worshipping Him Alone, and none else, and by doing righteous deeds sincerely for Allah's sake only, and not to show off, and not setting up rivals with Him in worship). All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists).

(50) Say (O Muhammad صلى الله عليه وسلم): "Do you verily disbelieve in Him Who created the earth in two Days? And you set up rivals (in worship) with Him? That is the Lord of the 'Alamin (mankind, jinn and all that exists).
