Tahdhīb al-Aḥkām|Volume 2|Book 1|Chapter 5
مُحَمَّدُ بْنُ يَعْقُوبَ عَنْ عَلِيِّ بْنِ مُحَمَّدٍ رَفَعَهُ قَالَ: قِيلَ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ لِمَ صَارَ اَلرَّجُلُ يَنْحَرِفُ فِي اَلصَّلاَةِ إِلَى اَلْيَسَارِ فَقَالَ« لِأَنَّ لِلْكَعْبَةِ سِتَّةَ حُدُودٍ أَرْبَعَةٌ مِنْهَا عَلَى يَسَارِكَ وَ اِثْنَانِ مِنْهَا عَلَى يَمِينِكَ فَمِنْ أَجْلِ ذَلِكَ وَقَعَ اَلتَّحْرِيفُ عَلَى اَلْيَسَارِ»
Narrated by Muhammad ibn Ya’qub from Ali ibn Muhammad, who raised it, said:
It was said to Abu Abdillah عليه السلام: "Why does a person turn slightly to the left during prayer?" Imam عليه السلام said: "Because the Ka’bah has six sides, four of them are on your left and two of them are on your right. Therefore, the slight turning is toward the left."
