Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَ رَوَى مَسْعَدَةُ بْنُ صَدَقَةَ: أَنَّ قَائِلاً قَالَ لِجَعْفَرِ بْنِ مُحَمَّدٍ عَلَيْهِ اَلسَّلاَمُ جُعِلْتُ فِدَاكَ إِنِّي أَمُرُّ بِقَوْمٍ نَاصِبِيَّةٍ وَ قَدْ أُقِيمَتْ لَهُمُ اَلصَّلاَةُ وَ أَنَا عَلَى غَيْرِ وُضُوءٍ فَإِنْ لَمْ أَدْخُلْ مَعَهُمْ فِي اَلصَّلاَةِ قَالُوا مَا شَاءُوا أَنْ يَقُولُوا أَ فَأُصَلِّي مَعَهُمْ ثُمَّ أَتَوَضَّأُ إِذَا اِنْصَرَفْتُ وَ أُصَلِّي قَالَ جَعْفَرُ بْنُ مُحَمَّدٍ عَلَيْهِ اَلسَّلاَمُ «سُبْحَانَ اَللَّهِ أَ فَمَا يَخَافُ مَنْ يُصَلِّي عَلَى غَيْرِ وُضُوءٍ أَنْ تَأْخُذَهُ اَلْأَرْضُ خَسْفاً.
Mas’adah ibn Sadaqah narrates that someone said to Jafar ibn Muhammad عليه السلام: "May I be your ransom! I pass by a group of Nasibis (those hostile to the AhlulBayt عليه السلام), and their prayer has been established while I am not in a state of wudu (ritual purity). If I do not join them in prayer, they will say whatever they wish about me. Should I then pray with them and perform wudu afterward and pray again?" Jafar ibn Muhammad عليه السلام responded: "Glory be to Allah سبحانه وتعالى! Does he not fear that if he prays without wudu, the earth would swallow him up?"
