عَنْهُ عَنْ عَلِيِّ بْنِ خَالِدٍ عَنْ أَحْمَدَ بْنِ اَلْحَسَنِ بْنِ عَلِيِّ بْنِ فَضَّالٍ عَنْ عَمْرِو بْنِ سَعِيدٍ اَلْمَدَائِنِيِّ عَنْ مُصَدِّقِ بْنِ صَدَقَةَ عَنْ عَمَّارِ بْنِ مُوسَى اَلسَّابَاطِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلرَّجُلِ يُصَلِّي رَكْعَتَيْنِ مِنَ اَلْوَتْرِ وَ يَنْسَى اَلثَّالِثَةَ حَتَّى يُصْبِحَ قَالَ« يُوتِرُ إِذَا أَصْبَحَ بِرَكْعَةٍ مِنْ سَاعَتِهِ»
From him, from Ali ibn Khalid, from Ahmad ibn Al-Hasan ibn Ali ibn Faddal, from Amr ibn Sa'id Al-Mada'ini, from Musaddiq ibn Sadaqah, from Ammar ibn Musa Al-Sabati, from Abu Abdillah عليه السلام, peace be upon him, who said:
I asked Imam عليه السلام about a man who prays two rak'ahs of the Witr and forgets the third until morning comes. Imam عليه السلام said: "He should perform the Witr when he wakes up with one rak'ah immediately."
