They are seven regions mentioned in the Qur'an cited by the scholar Tha'labi in his monumental work "Qisas al-Anbiya".
The first among them is Mecca, as Allah has said :
"Do they not see how We visit the land, diminishing it in its outlying parts?" (13:41; 21:44)
The second region is the land of Medina, as God has said:
"Was not God's earth spacious that you could have migrated therein?" (4:97)
"My Earth is spacious..." (29:56).
"And they indeed wished to scare you from the land, that they might drive you forth thence." (17:26)
The third is the land of Syria and that is His saying:
"Go into the Holy Land [which God has prescribed for you, and turn not back in your traces, or you shall suffer]..." (5:21)
"And we rescued him and Lot (and brought them) to the land which We have blessed for (all) peoples." (21:71)
The fourth region is Egypt. He has said:
"Thus we established Joseph in the land..." (12:21)
"Set me over the storehouses of the land. I am a skilled custodian," (12:55)
"Therefore I shall not go forth from this land" (12:80)
"Pharaoh exalted himself in the earth." (28:4)
"And make you viceroys in the land..." (7:129)
The fifth is the land of the East, for that is His saying:
"Gog and Magog are spoiling the land." (18:95)
The sixth is all of the lands, for He said:
"And there is not a beast on the earth but its sustenance depends on God..." (11:16)
"Time is not an animal in the earth, nor a flying creature on two wings, but they are people like you..." (6:38)
"And if all the trees on the earth were pens..." (31:27)
"Who has appointed the earth a resting-place for you." (2:22)
