Is prayer in the mosque obligatory, and does not praying therein lead to Allah's disapproval?

Prayer in the mosque is one of the greatest acts of drawing near to Allah. For the one who prays there, the angels seek forgiveness, he is rewarded for his footsteps, and the reward for his prayer is amplified due to the large congregation. The differing opinions of the jurists regarding the ruling on congregational prayer in the mosque have been mentioned.
