Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 4
مُحَمَّدُ بْنُ اَلْحَسَنِ اَلصَّفَّارُ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنْ أَحْمَدَ بْنِ عُمَرَ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ تَوَضَّأَ وَ نَسِيَ أَنْ يَمْسَحَ رَأْسَهُ حَتَّى قَامَ فِي اَلصَّلاَةِ قَالَ« مَنْ نَسِيَ مَسْحَ رَأْسِهِ أَوْ شَيْئاً مِنَ اَلْوُضُوءِ اَلَّذِي ذَكَرَهُ اَللَّهُ تَعَالَى فِي اَلْقُرْآنِ أَعَادَ اَلصَّلاَةَ».
Muhammad ibn al-Hasan al-Ṣaffar, from Yaʿqub ibn Yazid, from Ahmad ibn ʿUmar, who said:
I asked Abu al-Hasan عليه السلام about a man who performed Wuduʾ but forgot to wipe his head until he stood in prayer. Imam عليه السلام said: "Whoever forgets to wipe their head or any part of the Wuduʾ that Allah سبحانه وتعالى, the Exalted, has mentioned in the Quran must repeat the prayer."
