Yahya related to me from Malik from Zayd ibn Aslam that the
Messenger of Allah, may Allah bless him and grant him peace, said,
"When you marry a woman or buy a slave-girl, take her by the forelock
and ask for baraka. When you buy a camel, take the top of its hump,
and seek refuge with Allah from Shaytan."
Muwatta Malik Book 28, Hadith 56
