Hulb prayed along with the Prophet ﷺ. He used to turn to both his sides (sometimes to the left and sometimes to the right).  

أَنَّهُ صَلَّى مَعَ النَّبِيِّ ﷺ وَكَانَ يَنْصَرِفُ عَنْ شِقَّيْهِ  

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

لاَ يَجْعَلْ أَحَدُكُمْ نَصِيبًا لِلشَّيْطَانِ مِنْ صَلاَتِهِ أَنْ لاَ يَنْصَرِفَ إِلاَّ عَنْ يَمِينِهِ وَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ أَكْثَرَ مَا يَنْصَرِفُ عَنْ شِمَالِهِ قَالَ عُمَارَةُ أَتَيْتُ الْمَدِينَةَ بَعْدُ فَرَأَيْتُ مَنَازِلَ النَّبِيِّ ﷺ عَنْ يَسَارِهِ
