Silsilah Sahihah

Abdur Rahman bin Salim bin Utbah bin Uwaim bin Sa'idah narrates from his father, and he from his grandfather, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Marry virgins, for they are sweet in speech, very fertile, and content with little wealth."

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) said to me: "Jabir, do you have a wife?" I said: Yes. He (peace be upon him) asked: "Did you marry a widow or a virgin?" I replied: A widow. He (peace be upon him) said: "Why did you not marry a young girl?" I said: My father was martyred with you in such-and-such battle, and he left behind daughters. (Since I am their guardian,) I disliked marrying a girl like them. I married a widow so that she could remove lice from (my sisters) and sew their torn, old clothes. The Prophet (peace be upon him) said: "You have thought very well."

Lady Aisha (may Allah be pleased with her) says: I said, "O Messenger of Allah! If you were to descend in a valley where one tree has already been grazed upon and another tree is untouched, on which tree would you let your camel graze?" He (peace and blessings be upon him) said: "On the one which has not been used as fodder." The meaning of this hadith is that the Messenger of Allah (peace and blessings be upon him) did not marry any virgin woman except Lady Aisha (may Allah be pleased with her).
