وَجَٰوَزْنَا بِبَنِىٓ إِسْرَٰٓءِيلَ ٱلْبَحْرَ فَأَتَوْا۟ عَلَىٰ قَوْمٍۢ يَعْكُفُونَ عَلَىٰٓ أَصْنَامٍۢ لَّهُمْ ۚ قَالُوا۟ يَٰمُوسَى ٱجْعَل لَّنَآ إِلَٰهًۭا كَمَا لَهُمْ ءَالِهَةٌۭ ۚ قَالَ إِنَّكُمْ قَوْمٌۭ تَجْهَلُونَ
And We brought the Children of Israel across the sea, and they came unto a people who were given up to idols which they had. They said: O Moses! Make for us a god even as they have gods. He said: Lo! ye are a folk who know not.

Virtues of Madinah
Chapter: Ad-Dajjal will not be able to enter Al-Madina
Narrated Anas bin Malik:
The Prophet (ﷺ) said, "There will be no town which Ad-Dajjal will not enter except Mecca and Medina, and there will be no entrance (road) (of both Mecca and Medina) but the angels will be standing in rows guarding it against him, and then Medina will shake with its inhabitants thrice (i.e. three earthquakes will take place) and Allah will expel all the non-believers and the hypocrites from it."
