Musannaf Ibn Abi Shaybah

It is narrated from the wife of Abdullah bin Rawahah that Abdullah bin Rawahah had two mosques: one in his house and one in his room. When he wanted to go outside, he would pray in the mosque in his room, and when he wanted to come inside, he would pray in the mosque in his house. And wherever he found the time for prayer, he would make his animal sit down and pray.
