Consensus that the Earth is round

More than one of the scholars
have narrated that there is consensus that the Earth is round. For example: 

Shaykh al-Islam Ibn Taymiyah
(may Allah have mercy on him) narrated that from Abu’l-Husayn ibn al-Munaadi
(may Allah have mercy on him), when he said: 

Imam Abu’l-Husayn Ahmad ibn
Ja‘far ibn al-Munaadi narrated from the prominent scholars who are well
known for knowledge of reports and major works in religious sciences, from
the second level of Ahmad’s companions, that there was no difference of
opinion among the scholars that the sky is like a ball. 

He said: Similarly they were
unanimously agreed that the Earth, with all that is contains of land and sea
is like a ball. He said: That is indicated by the fact that the sun, moon
and stars do not rise and set over those who are in different parts of the
earth at the same time; rather that occurs in the east before it occurs in
the west.

End quote from Majmoo‘ al-Fataawa
(25/195) 

He (may Allah have mercy on him)
was asked about two men who disputed about the nature of heaven and earth:
were they both round bodies? One of them said that they were, but the other
denied that and said there is no basis for that. What is the correct view? 

He replied: 

The heavens are round, according
to the Muslim scholars. More than one of the scholars and Muslim leaders
narrated that the Muslims are unanimously agreed on that, such as
Abu’l-Husayn Ahmad ibn Ja‘far ibn al-Munaadi, one of the leading figures
among the second level of the companions of Imam Ahmad, who wrote
approximately four hundred books. Consensus on this point was also narrated
by Imam Abu Muhammad ibn Hazm and Abu’l-Faraj ibn al-Jawzi. The scholars
narrated that with well-known chains of narration (isnaads) from the
Sahaabah and Taabi‘een, and they quoted that from the Book of Allah and the
Sunnah of His Messenger. They discussed that in detail with
orally-transmitted evidence. There is also mathematical evidence to that
effect, and I do not know of anyone among the well-known Muslim scholars who
denied that, apart from a few of those who engaged in arguments who, when
they debated with the astrologers denied it for the sake of argument and
said: It may be square or hexagonal and so on. They did not deny that it
could be round, but they said that the opposite of that was possible. I do
not know of anyone who said that it is not round – with any certainty –
apart from some ignorant people to whom no one pays any attention.

End quote from Majmoo‘ al-Fataawa
(6/586) 

Abu Muhammad ibn Hazm (may Allah
have mercy on him) said: Evidence for the earth being round: 

Abu Muhammad said: We are going
to discuss some of the arguments against the idea that the earth is round.
They said: There is sound evidence that the earth is round, but the common
folk say otherwise. Our response – and Allah is the source of strength – is
that none of the leading Muslim scholars who deserve to be called imams or
leaders in knowledge (may Allah be pleased with them) denied that the earth
is round, and there is no narration from them to deny that. Rather the
evidence in the Qur’an and Sunnah stated that it is round. … and he quoted
evidence to that effect.

End quote from al-Fasl
fi’l-Milal wa’l-Ahwa’ wa’l-Nihal (2/78) 

The evidence that the earth is
round includes the following: 

Allah, may He be exalted, says
(interpretation of the meaning):

“He created the heavens and
earth for a true purpose; He wraps the night around the day and the day
around the night”

[az-Zumar 39:5]. 

Ibn Hazm and others quoted this
verse as evidence. 

Shaykh Ibn ‘Uthaymeen (may Allah
have mercy on him) said:

The earth is round, based on the
evidence of the Qur’an, reality, and scientific views. 

The evidence of the Qur’an is
the verse in which Allah, may He be exalted, says (interpretation of the
meaning):

“He created the heavens and
earth for a true purpose; He wraps the night around [yukawwir] the day and
the day around the night”

[az-Zumar 39:5].

The word yukawwir
(translated here as “wraps around” means to make something round, like a
turban. It is well-known that night and day follow one another on earth,
which implies that the Earth is round, because if you wrap one thing around
another thing, and the thing that it is wrapped around is the Earth, then
Earth must be round. 

With regard to real-life
evidence, this has been proven. If a man were to fly from Jeddah, for
example, heading west, he would come back to Jeddah from the east, if he
flew in a straight line. This is something concerning which no one differs. 

With regard to the words of the
scholars, they stated that if a man died in the east at sunset, and another
died in the west at sunset, and there was some distance between them, the
one who died in the west at sunset would inherit from the one who died in
the east at sunset, if he was one of his heirs. This indicates that the
earth is round, because if the earth were flat, sunset in all regions would
occur at the same time. Once this is established, no one can deny it. This
is not contradicted by the verses in which Allah, may He be exalted, says
(interpretation of the meaning): 

“Do they not look at the
camels, how they are created?

And at the heaven, how it is
raised?

And at the mountains, how
they are rooted and fixed firm?

And at the earth, how it is
spread out?”

[al-Ghaashiyah 88:17-20]
 

Because the Earth is huge and
its curvature cannot be seen from a short distance, it appears to be spread
out and one cannot see anything that would make one fear living on it, but
this does not contradict the fact that it is round, because it is very big.
However they say that it is not evenly round; rather it is indented or
pushed in at the north and south poles. Hence they say that it is
egg-shaped.

End quote from Fataawa Noor
‘ala ad-Darb 

Thus it is known that the Earth
is round, and that is not contradicted by the fact that it is like an egg.
Rather the false view is that which claims that it is flat, as the Church
used to believe and for that reason used to curse and burn those scientists
who said that it was round.

And Allah knows best.
