Prayers (Salat)
8/32. Chapter:
What has been said about (facing) the Qiblah (Kabah at Makkah) and wherever considered that there was no need to repeat the Salat (prayer) if someone offered prayers by mistake facing a direction other than that of the Qiblah
وَقَدْ سَلَّمَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي رَكْعَتَيِ الظُّهْرِ، وَأَقْبَلَ عَلَى النَّاسِ بِوَجْهِهِ، ثُمَّ أَتَمَّ مَا بَقِيَ.When the Prophet ﷺ did Taslim after offering two Rak'a of Zuhr prayer he then faced the people and then completed the rest of the prayer.
Sahih Bukhari
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ صَلَّى النَّبِيُّ صلى الله عليه وسلم الظُّهْرَ خَمْسًا فَقَالُوا أَزِيدَ فِي الصَّلاَةِ قَالَ " وَمَا ذَاكَ ". قَالُوا صَلَّيْتَ خَمْسًا. فَثَنَى رِجْلَيْهِ وَسَجَدَ سَجْدَتَيْنِ.
Narrated `Abdullah: "Once the Prophet (ﷺ) offered five rak`at in Zuhr prayer. He was asked, "Is there an increase in the prayer?" The Prophet (ﷺ) said, "And what is it?" They said, "You have prayed five rak`at.' So he bent his legs and performed two prostrations (of Sahu).
