حَدَّثَنِي يَحْيَى، عَنْ مَالِك، عَنْ
زَيْدِ بْنِ أَسْلَمَ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :
" إِذَا تَزَوَّجَ أَحَدُكُمُ الْمَرْأَةَ، أَوِ اشْتَرَى الْجَارِيَةَ، فَلْيَأْخُذْ بِنَاصِيَتِهَا، وَلْيَدْعُ بِالْبَرَكَةِ، وَإِذَا اشْتَرَى الْبَعِيرَ، فَلْيَأْخُذْ بِذِرْوَةِ سَنَامِهِ، وَلْيَسْتَعِذْ بِاللَّهِ مِنَ الشَّيْطَانِ "
It is narrated from Sayyiduna Zaid bin Aslam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When any of you marries a woman or buys a slave-girl, he should take hold of her forehead and pray for blessing, and when he buys a camel, he should place his hand on its hump and seek refuge from the accursed devil."
