‘Abd Allah (b. Mas’ud) said; One of you should not give a share from his prayer to the devil, that he does not turn away expect to his right side. I saw the Messenger of Allah (ﷺ) often turning away to his left side. the narrator ‘Umarah said:

I came to medina afterwards and saw that the houses of the prophet (ﷺ) were (built) in the left.

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنِ الأَسْوَدِ بْنِ يَزِيدَ، عَنْ عَبْدِ اللَّهِ، قَالَ لاَ يَجْعَلْ أَحَدُكُمْ نَصِيبًا لِلشَّيْطَانِ مِنْ صَلاَتِهِ أَنْ لاَ يَنْصَرِفَ إِلاَّ عَنْ يَمِينِهِ وَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم أَكْثَرَ مَا يَنْصَرِفُ عَنْ شِمَالِهِ ‏.‏ قَالَ عُمَارَةُ أَتَيْتُ الْمَدِينَةَ بَعْدُ فَرَأَيْتُ مَنَازِلَ النَّبِيِّ صلى الله عليه وسلم عَنْ يَسَارِهِ ‏.‏
