Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَ سَأَلَهُ يَعْقُوبُ بْنُ عُثَيْمٍ عَنْ سَامِّ أَبْرَصَ وَجَدْنَاهُ فِي اَلْبِئْرِ قَدْ تَفَسَّخَ فَقَالَ «إِنَّمَا عَلَيْكَ أَنْ تَنْزَحَ مِنْهَا سَبْعَةَ دِلاَءٍ فَقَالَ لَهُ فَثِيَابُنَا قَدْ صَلَّيْنَا فِيهَا نَغْسِلُهَا وَ نُعِيدُ اَلصَّلاَةَ قَالَ لاَ.
Yaqub ibn Uthaym asked Imam Muhammad ibn Ali Al-Baqir عليه السلام about a gecko that was found decayed in a well. Imam عليه السلام said: "You only need to draw seven buckets from it." Ya'qub then asked: "Our clothes that we prayed in—do we need to wash them and repeat the prayer?" Imam عليه السلام said: "No."
