Chapter on Tayammum and Its Rules
Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 8
يَدُلُّ عَلَيْهِ مَا أَخْبَرَنِي بِهِ اَلشَّيْخُ أَيَّدَهُ اَللَّهُ تَعَالَى عَنْ أَبِي اَلْقَاسِمِ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ يَعْقُوبَ عَنْ عَلِيِّ بْنِ إِبْرَاهِيمَ رَفَعَهُ قَالَ:« إِنْ أَجْنَبَ نَفْسَهُ فَعَلَيْهِ أَنْ يَغْتَسِلَ عَلَى مَا كَانَ مِنْهُ وَ إِنِ اِحْتَلَمَ تَيَمَّمَ».
It is supported by what was reported to me by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, from Abu al-Qasim Ja'far ibn Muhammad, from Muhammad ibn Ya'qub, from Ali ibn Ibrahim, who raised it (the narration):
"If a person deliberately causes himself to become in a state of janabah, then it is incumbent upon him to perform ghusl for what he has done. However, if he experiences a nocturnal emission (ihtilam), then he may perform tayammum."
