Numerical Miracles : Seven Heavens for Seven times and Seven of the Earth for only One time.
1.The quantity of Objects:
First of all,there are seven heavens (plural) but regarding Earth,it is Seven of the Earth (Earth is singular).
So the word seven of the Earth is mentioned only once while seven heavens is there 7 times in Quran.
It is He who created for you all of that which is on the earth. Then He directed Himself to the heaven, [His being above all creation], and made them seven heavens, and He is Knowing of all things.(Baqrah:29)
The seven heavens and the earth and whatever is in them exalt Him. And there is not a thing except that it exalts [ Allah ] by His praise, but you do not understand their [way of] exalting. Indeed, He is ever Forbearing and Forgiving.(Isra 44)
Say, “Who is Lord of the seven heavens and Lord of the Great Throne?”(Muminoon 86)
And He completed them as seven heavens within two days and inspired in each heaven its command. And We adorned the nearest heaven with lamps and as protection. That is the determination of the Exalted in Might, the Knowing.(Fussilat 12)
It is Allah who has created seven heavens and of the earth, the like of them. [His] command descends among them so you may know that Allah is over all things competent and that Allah has encompassed all things in knowledge.(Talaq 12)
[And] who created seven heavens in layers. You do not see in the creation of the Most Merciful any inconsistency. So return [your] vision [to the sky]; do you see any breaks?(Mulk 3)
Do you not consider how Allah has created seven heavens in layers(Nuh 15)
Seven of the Earth:
Earth is singular so the seven of the Earth is also mentioned for only one time,not seven times as the seven heavens.
It is Allah who has created seven heavens and of the earth, the like of them. [His] command descends among them so you may know that Allah is over all things competent and that Allah has encompassed all things in knowledge.
2.Discuss the one which has infinity and then go for something which is finite:
Secondly,and most importantly,note the following points:
1.The Universe is continuously expanding.The measurements/dimensions of space fall into infinity.
2.The diameter of Earth,its gravity and almost everything is measurable.Nothing falls into infinity.
The question of the critic is that why the Universe is discussed,the miracle of Universe is clear while not that of Earth?
The answer proves that Quran is truly revealed by Our Lord Allah.
Read the following research.
Research in mathematics education indicates that in the transition from given systems to wider ones prospective teachers tend to attribute all the properties that hold for the former also to the latter. In particular, it has been found that, in the context of Cantorian Set Theory, prospective teachers have been found to erroneously attribute properties of finite sets to infinite ones — using different methods to compare the number of elements in infinite sets. These methods which are acceptable for finite sets, lead to contradictions with infinite ones. This paper describes a course in Cantorian Set Theory that relates to prospective secondary mathematics teachers’ tendencies to overgeneralize from finite to infinite sets. The findings clearly indicate that when comparing the number of elements in infinite sets the prospective teachers who took the course were more successful and were also more consistent in their use of a single method than those who studied the traditional, formally based Cantorian Set Theory course.
The best way is to compare the number of elements in infinite sets to those of finite sets.Start from an infinite set.
