مُحَمَّدُ بْنُ عَلِيِّ بْنِ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ اَلسِّنْدِيِّ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنْ رَجُلٍ صَلَّى رَكْعَةً عَلَى تَيَمُّمٍ ثُمَّ جَاءَ رَجُلٌ وَ مَعَهُ قِرْبَتَانِ مِنْ مَاءٍ قَالَ« يَقْطَعُ اَلصَّلاَةَ وَ يَتَوَضَّأُ ثُمَّ يَبْنِي عَلَى وَاحِدَةٍ».
Muhammad ibn Ali ibn Mahbub narrated from Ali ibn al-Sindi, from Hammad, from Hariz, from Zurara, from Abu Ja’far (a.s): I asked Imam (a.s) about a man who prayed one rak'ah (unit of prayer) while performing tayammum (dry ablution), then another man arrived carrying two water skins. Imam Abu Ja’far (a.s) said: "He should discontinue his prayer, perform wudu (ablution), and then resume the prayer, continuing from the one rak'ah he already performed."
