Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 16
عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ زُرَارَةَ قَالَ قَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ:« إِنَّ اَللَّهَ وَتْرٌ يُحِبُّ اَلْوَتْرَ فَقَدْ يُجْزِيكَ مِنَ اَلْوُضُوءِ ثَلاَثُ غُرَفَاتٍ وَاحِدَةٌ لِلْوَجْهِ وَاِثْنَتَانِ لِلذِّرَاعَيْنِ وَ تَمْسَحُ بِبِلَّةٍ يُمْنَاكَ نَاصِيَتَكَ وَ مَا بَقِيَ مِنْ بِلَّةِ يُمْنَاكَ ظَهْرَ قَدَمِكَ اَلْيُمْنَى وَ تَمْسَحُ بِبِلَّةِ يُسْرَاكَ ظَهْرَ قَدَمِكَ اَلْيُسْرَى»
Narrated by Ali ibn Ibrahim, from his father, from Hammad ibn Isa, from Hariz, from Zurara.
Abu Ja‘far عليه السلام, said: "Indeed, Allah سبحانه وتعالى is One and loves odd numbers. Therefore, it suffices you in ablution to use three handfuls of water - one for face and two for arms. Then, you wipe your forehead with the moisture remaining in your right hand, and with what is left of the moisture in your right hand, you wipe the top of your right foot. And you wipe the top of your left foot with the moisture remaining in your left hand."
