Hadith 2:402
Narrated Hudhaifah (RA):
The Prophet (ﷺ) performed Salatal-Khauf leading these (Companions) in one Rak'ah and those (other Companions) in one Rak'ah, and they did not make up the second Rak'ah. [Reported by Ahmad, Abu Dawud and an-Nasa'i. Ibn Hibban graded it Sahih (authentic)].
وَعَنْ حُذَيْفَةَ: { أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -صَلَّى صَلَاةَ اَلْخَوْفِ بِهَؤُلَاءِ رَكْعَةً, وَبِهَؤُلَاءِ رَكْعَةً, وَلَمْ يَقْضُوا } رَوَاهُ أَحْمَدُ, وَأَبُو دَاوُدَ, وَالنَّسَائِيُّ, وَصَحَّحَهُ ابْنُ حِبَّانَ
