لَوْ كَانَ عَرَضًۭا قَرِيبًۭا وَسَفَرًۭا قَاصِدًۭا لَّٱتَّبَعُوكَ وَلَٰكِنۢ بَعُدَتْ عَلَيْهِمُ ٱلشُّقَّةُ ۚ وَسَيَحْلِفُونَ بِٱللَّهِ لَوِ ٱسْتَطَعْنَا لَخَرَجْنَا مَعَكُمْ يُهْلِكُونَ أَنفُسَهُمْ وَٱللَّهُ يَعْلَمُ إِنَّهُمْ لَكَٰذِبُونَ
Had it been a near adventure and an easy journey they had followed thee, but the distance seemed too far for them. Yet will they swear by Allah (saying): If we had been able we would surely have set out with you. They destroy their souls, and Allah knoweth that they verily are liars.

Virtues of Madinah
Chapter: The dislike of the Prophet (saws) that Al-Madina should be vacated
Narrated Anas:
(The people of) Bani Salama intended to shift near the mosque (of the Prophet) but Allah's Messenger (ﷺ) disliked to see Medina vacated and said, "O the people of Bani Salama! Don't you think that you will be rewarded for your footsteps which you take towards the mosque?" So, they stayed at their old places.
