Mishkat al-Masabih, 1114

‘A’isha said that God’s Messenger prayed in his private apartment and the people followed his lead behind the apartment. Abu Dawud transmitted it.

وَعَنْ عَائِشَةَ رِضَى اللَّهُ عَنْهَا قَالَتْ: صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي حُجْرَتِهِ وَالنَّاسُ يَأْتَمُّونَ بِهِ مِنْ وَرَاءِ الْحُجْرَةِ. رَوَاهُ أَبُو دَاوُد
