What is the ruling on congregational prayer?

Question:
This person is asking about congregational prayer. Prayer in congregation is equivalent to

Answer:
twenty-four or twenty-seven prayers. This is the favor of Allah (Glorified and Exalted is He). This indicates the virtue of congregational prayer. Prayer in congregation is better than prayer alone. Prayer alone is equivalent to one prayer, and prayer in congregation is equivalent to twenty-seven prayers. What is the difference between one and twenty-seven?
This indicates the virtue of congregational prayer and that Allah gives the reward of twenty-seven prayers. However, if a man prays alone without an excuse, he has no reward except for one prayer. If someone said to you, "Choose: I will give you one riyal or I will give you twenty-seven riyals," would you say, "I want the one riyal"? No. If you took the one riyal, people would say, "You are not sane. You are not of sound mind. You are a fool. How can you leave twenty-seven riyals and take one riyal?" Therefore, the one who prays and leaves congregational prayer to pray alone is a fool, because he left the profit and the trade of the Hereafter for nothing but laziness. This is, in reality, negligence and waste.
The rest of his question is about a man praying in the wilderness. A man who has no congregation, who calls the adhan in the wilderness and prays, has a great reward. The earth testifies for him, hearing his call to prayer (adhan) while he prays alone, because he has no congregation. But if he has a congregation, it is not permissible for him to pray alone, even in the wilderness. If there are two or more, it is not permissible for each one to pray for himself. They must pray together. Yes.
