Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 30
وَ رَوَى زُرَارَةُ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «فَرَضَ اَللَّهُ عَزَّ وَ جَلَّ اَلصَّلاَةَ وَ سَنَّ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ عَشَرَةَ أَوْجُهٍ صَلاَةَ اَلسَّفَرِ وَ صَلاَةَ اَلْحَضَرِ وَ صَلاَةَ اَلْخَوْفِ عَلَى ثَلاَثَةِ أَوْجُهٍ وَ صَلاَةَ كُسُوفِ اَلشَّمْسِ وَ اَلْقَمَرِ وَ صَلاَةَ اَلْعِيدَيْنِ وَ صَلاَةَ اَلاِسْتِسْقَاءِ وَ اَلصَّلاَةَ عَلَى اَلْمَيِّتِ.
Zurarah narrated from Imam Muhammad ibn Ali Al-Baqir عليه السلام that He said: "Allah سبحانه وتعالى, the Mighty and Majestic, made prayer obligatory, and the Messenger of Allah صلى الله عليه وعلى آله وسلم established it in ten forms: the prayer during travel, the prayer while residing, the prayer of fear in three forms, the prayer during the eclipse of the sun and moon, the prayers of the two Eid’s, the prayer for rain (Salat al-Istisqa), and the funeral prayer."
