Hadith 530090
Chapter 45: Madina - كتاب الْمَدِينَةِ
وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، حِينَ خَرَجَ مِنَ الْمَدِينَةِ الْتَفَتَ إِلَيْهَا فَبَكَى ثُمَّ قَالَ يَا مُزَاحِمُ أَتَخْشَى أَنْ نَكُونَ مِمَّنْ نَفَتِ الْمَدِينَةُ
Malik related to me that he had heard that when Umar ibn Abd al- Aziz left Madina, he turned towards it and wept. Then he said, "O Muzahim! Do you fear that we might be among those that Madina casts off?"
