question #3 Sahih Muslim 664, Book 5, Hadith 351 : Why might the Prophet Muhammad (ﷺ) have discouraged selling homes to move closer to a mosque?

Our houses were situated far away from the mosque; we, therefore, decided to sell our houses so that we may be able to come near the mosque. The Messenger of Allah (ﷺ) forbade us (to do so) and said: There is for every step (towards the mosque) a degree (of reward) for you.
