Tahdhīb al-Aḥkām|Volume 2|Book 1|Chapter 5
مُحَمَّدُ بْنُ يَعْقُوبَ عَنْ مُحَمَّدِ بْنِ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ زُرَارَةَ قَالَ قَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ:« يُجْزِي اَلتَّحَرِّي أَبَداً إِذَا لَمْ يُعْلَمْ أَيْنَ وَجْهُ اَلْقِبْلَةِ»
Narrated by Muhammad ibn Ya’qub from Muhammad ibn Yahya from Ahmad ibn Muhammad from Hammad from Hariz from Zurarah, who said:
Abu Ja’far عليه السلام said: "Estimation (taharri) is always sufficient when the direction of the qiblah is not known."
