Keringanan shalat satu rakaat bagi orang ketika dalam keadaan takut
Imam Abu Dawud : 1056حَدَّثَنَا مُسَدَّدٌ وَسَعِيدُ بْنُ مَنْصُورٍ قَالَا حَدَّثَنَا أَبُو عَوَانَةَ عَنْ بُكَيْرِ بْنِ الْأَخْنَسِ عَنْ مُجَاهِدٍ عَنْ ابْنِ عَبَّاسٍ قَالَفَرَضَ اللَّهُ تَعَالَى الصَّلَاةَ عَلَى لِسَانِ نَبِيِّكُمْ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةً
Narrated to us [Musaddad] and [Sa'id bin Manshur] both said: Narrated to us [Abu 'Awanah] from [Bukair bin Al Ahnas] from [Mujahid] from [Ibn Abbas] he said: 'Allah Ta'ala has obligated prayer through the tongue of your Prophet when residing (not traveling) four raka'at, during travel two raka'at, and in a state of fear (during war) one raka'at.'
