What Defiles Clothing and the Body
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 17
وَ سَأَلَ حَنَانُ بْنُ سَدِيرٍ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ فَقَالَ - إِنِّي رُبَّمَا بُلْتُ فَلاَ أَقْدِرُ عَلَى اَلْمَاءِ وَ يَشْتَدُّ ذَلِكَ عَلَيَّ فَقَالَ «إِذَا بُلْتَ وَ تَمَسَّحْتَ فَامْسَحْ ذَكَرَكَ بِرِيقِكَ فَإِنْ وَجَدْتَ شَيْئاً فَقُلْ هَذَا مِنْ ذَاكَ.
Hanan ibn Sudair asked Imam Jafar ibn Muhammad Al-Sadiq عليه السلام saying: 'Sometimes I urinate and cannot find water, and it becomes difficult for me.' Imam عليه السلام said: 'If you urinate and dry yourself, then wipe your private part with your saliva. If you notice anything afterward, say, "This is from that."'.
