As for urination...

📌As for urination, however, it is a must to wash oneself (with water after urinating).[^14] Note: He has also narrated it in al-Istibsar.[^15] In al-Tahdhib: From Ahmad ibn Muhammad, from some of our companions quoting from Abi ‘Abdillah (as) who said: It was (from) the sunnah to use three clean stones for cleansing oneself, followed by water.[^16] In al-Da’aim: ‘Ali (as) said: The sunnah with regards to cleansing oneself with water is to start with (washing away) the urine and then the stool and not (to wash) both at once.[^17] Also: When he (S) wanted to relieve himself during a journey, he would move far away (from the people) and find a hidden place.[^18] Also: They (the Imams (as)) narrated: When the Holy Prophet (S) entered the lavatory, he would cover his head and veil himself and nobody ever saw him.[^19] [^1]: Fawa`id al-Milliyyah fi Sharh al-Nafliyyah: 17, ‘Awarif al-Ma’arif: 261, Da`aim al-Islam 1:104 [^2]: al-Ja’fariyat: 30, Da`aim al-Islam 1:104, al-Mustadrak 1:248 [^3]: Amali al-Tusi 2:147, Majmu`at Warram: 307, Makarim al-Akhlaq: 465 [^4]: al-Muqni`ah: 39, Tahdhib al-Ahkam 1:24 [^5]: al-Ja’fariyat: 12, al-Mustadrak 1:260 [^6]: al-Kafi 6:373, `Uyun Akhbar al-Rid’a 2:55 [^7]: Makarim al-Akhlaq: 92, al-Ja’fariyat: 186 [^8]: al-Khisal: 192 [^9]: Tahdhib al-Ahkam 1:33, ‘Ilal al-Shara’i: 278, al-Faqih 1:22 [^10]: al-Ja’fariyat: 14 [^11]: al-Hidayah: 15 [^12]: al-Kafi 3:69 [^13]: ‘Ilal al-Shara’i: 276, we have not found this in al-Mahasin.
