Virtues of Madinah

Narrated Anas (Radi-Allahu 'anhu):

(The people of) Bani Salama intended to shift near the mosque (of the
Prophet) but Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) 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.
