Chapter 48: Qust (incense) may be used by a mourning after being cleaned from her menses.
We were forbidden to mourn for more than three days for a dead person, except for a husband, for whom a wife should mourn for four months and ten days (while in the mourning period) we were not allowed to put kohl in our eyes, nor perfume our-selves, nor wear dyed clothes, except a garment of 'Asb (special clothes made in Yemen). But it was permissible for us that when one of us became clean from her menses and took a bath, she could use a piece of a certain kind of incense. And it was forbidden for us to follow funeral processions.
Chapter 53: The gift given by a husband to a divorced lady for whom Mahr has not been fixed.
The Prophet (ﷺ) said to those who were involved in a case of Lian, "Your accounts are with Allah. One of you two is a liar. You (husband) have right on her (wife)." The husband said, "My money, O Allah's Apostle!" The Prophet (ﷺ) said, "You are not entitled to take back any money. If you have told the truth, the Mahr that you paid, was for having sexual relations with her lawfully; and if you are a liar, then you are less entitled to get it back."
