The Chapter of the Qibla
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 43
وَقَالَ عَلَيْهِ اَلسَّلاَمُ لِزُرَارَةَ: «لاَ تُعَادُ اَلصَّلاَةُ إِلاَّ مِنْ خَمْسَةٍ اَلطَّهُورِ وَ اَلْوَقْتِ وَ اَلْقِبْلَةِ وَ اَلرُّكُوعِ وَ اَلسُّجُودِ.
Imam عليه السلام said to Zurarah: "The prayer is not to be repeated except for five things: purification (taharah), time (observing the prayer time), facing the Qiblah, bowing (ruku'), and prostration (Sujood)”.
