Narrated `Uqba: The Prophet said: "The stipulations most entitled to be abided by are those with which you are given the right to enjoy the (women's) private parts (i.e. the stipulations of the marriage contract).

Ibn Mas’ud (may Allah be pleased with him) said that no woman (co-wife) should stipulate the divorce of her sister.

Narrated Abu Huraira: The Prophet said, "It is not lawful for a woman (at the time of wedding) to ask for the divorce of her sister (i.e. the other wife of her would-be husband) in order to have everything for herself, for she will take only what has been written for her."

This narration has been reported by Abdur-Rahman bin Awf (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him).

Narrated Anas bin Malik: `Abdur-Rahman bin `Auf came to Allah's Apostle and he had marks of Sufra (yellow perfume). Allah's Apostle asked him (about those marks). `AbdurRahman bin `Auf told him that he had married a woman from the Ansar. The Prophet asked, "How much Mahr did you pay her?" He said, "I paid gold equal to the weight of a date stone." Allah's Apostle said to him, "Give a wedding banquet, even if with one sheep."

Narrated Anas: The Prophet offered a wedding banquet on the occasion of his marriage to Zainab, and provided a good meal for the Muslims. Then he went out as was his custom on marrying, he came to the dwelling places of the mothers of the Believers (i.e. his wives) invoking good (on them), and they were invoking good (on him). Then he departed (and came back) and saw two men (still sitting there). So he left again. I do not remember whether I informed him or he was informed (by somebody else) of their departure).

Narrated Anas: The Prophet saw the traces of Sufra (yellow perfume) on `Abdur-Rahman bin `Auf and said, "What is this?" `Abdur-Rahman, said, "I have married a woman and have paid gold equal to the weight of a datestone (as her Mahr). The Prophet said to him, "May Allah bless you: Offer a wedding banquet even with one sheep."

Narrated `Aisha: When the Prophet married me, my mother came to me and made me enter the house where I saw some women from the Ansar who said, "May you prosper and have blessings and have good omen."

Narrated Abu Huraira: The Prophet said, "A prophet among the prophets went for a military expedition and said to his people: "A man who has married a lady and wants to consummate his marriage with her and he has not done so yet, should not accompany me.' "

Narrated 'Urwa: The Prophet wrote the (marriage contract) with `Aisha while she was six years old and consummated his marriage with her while she was nine years old and she remained with him for nine years (i.e. till his death).
