Hadith #54

رَوَى أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنْ عَبْدِ اَللَّهِ بْنِ عَلِيٍّ اَلْحَلَبِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: أَنَّهُ قَالَ فِي رَجُلٍ يُصَلِّي بِالْقَوْمِ ثُمَّ يَعْلَمُ أَنَّهُ صَلَّى بِهِمْ إِلَى غَيْرِ اَلْقِبْلَةِ فَقَالَ« لَيْسَ عَلَيْهِمْ إِعَادَةُ شَيْءٍ»

Ahmad ibn Muhammad ibn Isa narrated from Muhammad ibn Abi Umayr, from Hammad ibn Uthman, from Abdillah ibn Ali al-Halabi, from Abu Abdillah , peace be upon him: Imam al-Sadiq said regarding a man who leads a group in prayer, then comes to know that he had led them facing other than the qiblah. Imam said: “There is nothing upon them to repeat.”
