Muhammad ibn Ahmad ibn Yahya, from Muhammad ibn Abd Al-Hamid, from Saif ibn Amira, from Mansur ibn Hazim, who said Muhammad ibn Ali Al-Halabi narrated: Abu Abdullah عليه السلام was asked regarding a man who experienced janabah (major ritual impurity) while in the desert and had only one garment, which was stained with semen. Imam عليه السلام said: "He should perform tayammum (dry ablution), remove his garment, sit closely together (covering himself as much as possible), and pray by gesturing (for bowing and prostration)."
