‘Ali reported the Prophet as saying, “There is no divorce before marriage, no manumission till one has possession, no continuous fasting, no orphan hood after the age of puberty, no suckling after weaning, and no silence all day up to the night”.*
* Observing a complete day's silence as a religious practice is rejected.
‘Amr b. Shu'aib, on his father’s authority, said his grandfather reported God’s Messenger as saying, “No descendant of Adam may make a vow about what he does not possess, or set free what he does not possess, or divorce what he does not possess.”
Tirmidhi transmitted it, and Abu Dawud added, “or sell what he does not possess.”
Thauban reported God's Messenger as saying, “If any woman asks her husband for divorce without some strong reason the odour of paradise will be forbidden to her.”
Ahmad, Tirmidhi, Abu Dawud, Ibn Majah and Darimi transmitted it.
