Dua The groom’s supplication on the wedding night or when buying an animal

اللَّهُمَّ إِنِّي أَسْأَلُكَ خَيْرَهَا، وَخَيْرَ مَا جَبَلْتَهَا عَلَيْهِ، وَأَعُوذُ بِكَ مِنْ شَرِّهَا، وَشَرِّ مَا جَبَلْتَهَا عَلَيْهِ ⁽¹⁾.

when you marry a woman or buy a maidservant, you should say: Allahumma innee as-aluka khayraha wakhayra ma jabaltaha AAalayh, wa-aAAoothu bika min sharriha washarri ma jabaltaha AAalayh.
‘O Allah, I ask You for the goodness within her and the goodness that you have made her inclined towards, and I take refuge with You from the evil within her and the evil that you have made her inclined towards.’ …and if you buy a camel, then you should take hold of it’s hump and say likewise.
