Sahih Bukhari | Volume 7 | Hadith Number 56
Narrated by Zainab bint Salama
Um Habiba said to Allah's Apostle "We have heard that you want to marry Durra bint Abu-Salama." Allah's Apostle said, "Can she be married along with Um Salama (her mother)? Even if I have not married Um Salama, she would not be lawful for me to marry, for her father is my foster brother." 'And there is no blame on you if you make hint of betrothal or conceal it in your hearts. Allah is Oft-Forgiving, Most Forbearing.' (2:235) Ibn 'Abbas said, "Hint your intention of marrying' is made by saying (to the widow) for example: "I want to marry, and I wish that Allah will make a righteous lady available for me.' " Al-Qasim said: One may say to the widow: 'I hold all respect for you, and I am interested in you; Allah will bring you much good, or something similar 'Ata said: One should hint his intention, and should not declare it openly. One may say: 'I have some need. Have good tidings. Praise be to Allah; you are fit to remarry.' She (the widow) may say in reply: I am listening to what you say,' but she should not make a promise. Her guardian should not make a promise (to somebody to get her married to him) without her knowledge. But if, while still in the Iddat period, she makes a promise to marry somebody, and he ultimately marries her, they are not to be separated by divorce (i.e., the marriage is valid).
