Chapter on Tayammum (dry ablution) and Its Rules

Muhammad ibn Ahmad, from Ya’qub ibn Yazid, from Al-Nadr ibn Suwayd, from Abdullah ibn Sinan, from Abu Hamzah, who said: Abu Ja’far عليه السلام said: "If a man is sleeping in Al-Masjid Al-Haram or the Mosque of the Messenger (may Allah سبحانه وتعالى bless him and his family) and experiences a wet dream, resulting in janabah (major ritual impurity), he should perform tayammum (dry ablution) and should not pass through the mosque except in a state of tayammum. However, there is no harm in passing through other mosques, but he should not sit in any of the mosques."
