[Machine] "I prayed with the Prophet ﷺ two units of prayer while travelling."  

«صَلَّيْتُ مَعَ النَّبِيِّ ﷺ فِي السَّفَرِ رَكْعَتَيْنِ»  

Allah has prescribed the prayer through the word of your Prophet ﷺ as four rak'ahs when resident, two when travelling, and one when danger is present. (Using translation from Muslim 687a)  

«إِنَّ اللهَ فَرْضَ الصَّلَاةَ عَلَى لِسَانِ نَبِيِّكُمْ ﷺ فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةٌ»
