Translation of the verse 30 from Surah An-Nazi‘at : Number of verses 46 - - page 584 - Part 30.
And after that He spread the earth;
And after that He spread the earth.
(79:30) and thereafter spread out the earth, *16
*16) "After that He spread out the earth" does not mean that Allah created the earth after the creation of the heavens, but it is a style of expression just like our saying after making mention of something: "Then this is noteworthy." The object is not to express the sequence of occurrence between the two things but to draw attention from the first to the second thing although both may exist together. Several instances of this style are found in the Qur'an, e.g. in Surah Al-Qalam it is said: "(He is) oppressive, and after that, ignoble by birth." This dces not mean that first he became oppressive and then he turned ignoble by birth, but it means: "He is oppressive, and above alI, ignoble by birth." Likewise, in Surah Al-Balad it is said: "Should free a slave...then be of those who believe." This also dces not mean that first he should act righteously and then believe. but that along with doing righteous deeds he should also be characterised by belief. Here, one should also understand that at some places in the Qur'an the creation of the earth has been mentioned first and then the creation of the heavens, as in Al-Baqarah: 29, and at others the creation of the heavens has been mentioned first and then of the earth, as in these verses. There is, in fact, no contradiction in this. At no place the object is to tell what was created first and what afterwards, but wherever the context requires that the excellences of the power of AIlah be made prominent, the heavens have been mentioned first and then the earth, and where the context requires that the people be made to appreciate and acknowledge the blessings that they are benefiting by on the earth, the mention of the earth has been made before that of the heavens. (For further explanation, see E.N's 13,14 of Ha Mim As-Sajdah).
