Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 22
وَ بِهَذَا اَلْإِسْنَادِ: عَنِ اَلرَّجُلِ يَنْكَسِرُ سَاعِدُهُ أَوْ مَوْضِعٌ مِنْ مَوَاضِعِ اَلْوُضُوءِ فَلاَ يَقْدِرُ أَنْ يَمْسَحَ عَلَيْهِ بِحَالِ اَلْجَبْرِ إِذْ أُ جْبِرَ كَيْفَ يَصْنَعُ قَالَ« إِذَا أَرَادَ أَنْ يَتَوَضَّأَ فَلْيَضَعْ إِنَاءً فِيهِ مَاءٌ وَ يَضَعُ مَوْضِعَ اَلْجَبْرِ فِي اَلْمَاءِ حَتَّى يَصِلَ اَلْمَاءُ إِلَى جِلْدِهِ وَ قَدْ أَجْزَأَهُ ذَلِكَ مِنْ غَيْرِ أَنْ يَحُلَّهُ».
And through this chain (of H.1353), Imam عليه السلام was asked regarding a man whose forearm or any part of his wudu (ablution) areas is broken and he cannot wipe over it due to a splint or cast, how should he perform wudu? Imam عليه السلام said: "When he wants to perform wudu, he should place a container with water and immerse the area with the splint into the water until the water reaches the skin beneath it. This suffices for him without needing to remove the splint."
