Hadith 10598ـ أَحْمَدُ بْنُ إِدْرِيسَ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ أَحْمَدَ بْنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ عَمْرِو بْنِ سَعِيدٍ عَنْ مُصَدِّقِ بْنِ صَدَقَةَ عَنْ عَمَّارٍ السَّابَاطِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ فِي رَجُلٍ صَلَّى عَلَى غَيْرِ الْقِبْلَةِ فَيَعْلَمُ وَهُوَ فِي الصَّلاَةِ قَبْلَ أَنْ يَفْرُغَ مِنْ صَلاَتِهِ قَالَ إِنْ كَانَ مُتَوَجِّهاً فِيمَا بَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ فَلْيُحَوِّلْ وَجْهَهُ إِلَى الْقِبْلَةِ سَاعَةَ يَعْلَمُ وَإِنْ كَانَ مُتَوَجِّهاً إِلَى دُبُرِ الْقِبْلَةِ فَلْيَقْطَعِ الصَّلاَةَ ثُمَّ يُحَوِّلُ وَجْهَهُ إِلَى الْقِبْلَةِ ثُمَّ يَفْتَتِحُ الصَّلاَةَ.
8. Ahmad ibn Idris and Muhammad ibn Yahya have narrated from Muhammad ibn Ahmad from Ahmad ibn al-Hassan ibn Ali from ‘Amr ibn Sa‘id from Musaddiq ibn Sadaqah from ‘Ammar al-Sabatiy who has said the following: “Abu ’Abd Allah (a.s.), has said that a man may perform a Salah (prayer) without facing proper al-Qiblah (al-Ka‘bah). He may realize it before completing the Salah (prayer). If his face is within one hundred eighty degrees of the al-Qiblah (al-Ka‘bah) he must turn to al-Qiblah (al-Ka‘bah) as soon as he realizes. If his back is toward al-Qiblah (al-Ka‘bah), he must discontinue the Salah (prayer), then turn to al-Qiblah (al-Ka‘bah) and begin the Salah (prayer) again.”’
