What was the instruction given by the Prophet Muhammad (peace be upon him) when he heard people wanted to sell their houses to be able to come close to the mosque?
 Jabir b. 'Abdullah narrated:                      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 (may peace be upon him) forbade us (to do so) and said: There is for every step (towards the mosque) a degree (of reward) for you.
