Hadith 13311339 - وَ رَوَى زُرَارَةُ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ صَلاَةُ اَلْخَوْفِ وَ صَلاَةُ اَلسَّفَرِ تُقْصَرَانِ جَمِيعاً قَالَ «نَعَمْ وَ صَلاَةُ اَلْخَوْفِ أَحَقُّ أَنْ تُقْصَرَ مِنْ صَلاَةِ اَلسَّفَرِ لِأَنَّ فِيهَا خَوْفاً.
Hadith.1339 – Zurarah narrated from Imam Muhammad ibn Ali Al-Baqir (as):
I asked him about the prayer of fear and the prayer of travel—are both to be shortened?
Imam (as) said: "Yes, and the prayer of fear is more deserving of being shortened than the prayer of travel because it involves fear”.
