Hadiths 7.96 and 7.97

7.96:
Narrated Anas:
When `Abdur−Rahman bin `Auf married an Ansari woman, the
Prophet asked him, "How much Mahr did you give her?"
`Abdur−Rahman said, "Gold equal to the weight of a date
stone." Anas added: When they (i.e. the Prophet and his
companions) arrived at Medina, the emigrants stayed at the
Ansar's houses. `Abdur−Rahman bin `Auf stayed at Sa`d bin
Ar−Rabi's house. Sa`d said to `Abdur−Rahman, "I will divide
and share my property with you and will give one of my two
wives to you." `Abdur−Rahman said, "May Allah bless you, your
wives and property (I am not in need of that; but kindly show
me the way to the market)." So `Abdur−Rahman went to the
market and traded there gaining a profit of some dried yoghurt
and butter, and married (an Ansari woman). The Prophet said to
him, "Give a banquet, even if with one sheep."

7.97:
Narrated Anas:
The Prophet did not give a better wedding banquet on the
occasion of marrying any of his wives than the one he gave on
marrying Zainab, and that banquet was with (consisted of) one
sheep.
