مُوَطَّأُ مَالِكٍ
Muwatta Malik 1147
Marriage
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ إِذَا تَزَوَّجَ أَحَدُكُمُ الْمَرْأَةَ أَوِ اشْتَرَى الْجَارِيَةَ فَلْيَأْخُذْ بِنَاصِيَتِهَا وَلْيَدْعُ بِالْبَرَكَةِ وَإِذَا اشْتَرَى الْبَعِيرَ فَلْيَأْخُذْ بِذِرْوَةِ سَنَامِهِ وَلْيَسْتَعِذْ بِاللَّهِ مِنَ الشَّيْطَانِ .
Yahya related to me from Malik from Zayd ibn Aslam that the Messenger of Allah, (ﷺ), 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."
