Chapter on Etiquettes of Causes Requiring Purification

Narrated to me by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, who said: Abu Al-Qasim Ja'far bin Muhammad narrated to me, from Muhammad bin Ya'qub, from Ali bin Ibrahim, through an elevated chain, who said: Abu Hanifa left the presence of Abu Abdullah عليه السلام, and Abu Al-Hasan Musa عليه السلام, who was still a young boy, was standing. Abu Hanifa said to him (Imam Al Kadhim): 'O boy, where should a stranger relieve himself in your town?' Imam عليه السلام replied: 'Avoid the courtyards of mosques, the banks of rivers, beneath fruit-bearing trees, places frequented by travelers, and do not face the Qiblah when defecating or urinating. Lift your garment, and then relieve yourself wherever you wish.'
