Tahdhīb al-Aḥkām|Volume 3|Book 2|Chapter 7
أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَ: فِي قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ« فَلَيْسَ عَلَيْكُمْ جُنٰاحٌ أَنْ تَقْصُرُ وا مِنَ اَلصَّلاٰةِ إِنْ خِفْتُمْ أَنْ يَفْتِنَكُمُ اَلَّذِينَ كَفَرُوا» قَالَ« فِي اَلرَّكْعَتَيْنِ يَنْقُصُ مِنْهُمَا وَاحِدَةٌ»
Ahmad ibn Muhammad from Hammad ibn Isa from Hariz from Abu Abdillah عليه السلام, peace be upon him:
Imam al-Sadiq عليه السلام was asked regarding the saying of Allah سبحانه وتعالى, the Mighty and Majestic: ‘Then there is no blame upon you if you shorten the prayer, if you fear that those who disbelieve may harm you’ (Surah An Nisa 4:101) Imam عليه السلام said: “In (from) the two rak‘ahs, one is reduced from them.”
