Muhammad ibn al-Hasan al-Saffar, from Muhammad ibn Isa, who said: Sulayman ibn Hafs al-Marwazi narrated to me, saying: I (narrator) heard Imam عليه السلام say: “If the fasting person rinses his mouth in the month of Ramadan, or sniffs water into his nose deliberately, or smells a thick odor, or sweeps a house and dust enters his nose or his throat, then upon him is the fasting of two consecutive months, for that is a breaking of the fast for him, like (the acts that break the fast) such as eating, drinking, and intercourse.”
