Allah's Messenger (ﷺ) made a small room in the month of Ramadan (Sa`id said, "I think that Zaid bin Thabitsaid that it was made of a mat") and he prayed there for a few nights, and so some of his companionsprayed behind him. When he came to know about it, he kept on sitting. In the morning, he went out tothem and said, "I have seen and understood what you did. You should pray in your houses, for the bestprayer of a person is that which he prays in his house except the compulsory prayers."
