They were the forefathers and you are the descendants
Allaah (The Most High) said:
[قَدۡ خَلَتۡ مِن قَبۡلِكُمۡ سُنَنٌ۬ فَسِيرُواْ فِى ٱلۡأَرۡضِ فَٱنظُرُواْ كَيۡفَ كَانَ عَـٰقِبَةُ ٱلۡمُكَذِّبِينَ ]
‘‘Many similar ways were faced by nations that have passed away before you, so travel through the earth, and see what was the end of those who disbelieved.” [3:137]
Indeed those nations that have passed away were nations like yourselves, so ponder upon their evil end. You should know that the reason they were destroyed was due to their denial of the Aayaat of Allaah and His Messengers. They were the forefathers and you are the descendants and the connection between you and them is that you all deny the Aayaat and the Messengers, and the verdict on all of you is that you’ll be destroyed.
