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

1. إِذَا تَزَوَّجَ أَحَدُكُمْ اِمْرَأَةً، أَوْ إِذَا اِشْتَرَى خَادِمًا فَلْيَقُلْ: (اللَّهُمَّ إِنِّي أَسْأَلُكَ خَيْرَهَا وَخَيْرَ مَا جَبَلْتَهَا عَلَيْهِ وَأَعُوذُ بِكَ مِنْ شَرِّهَا وَشَرِّ مَا جَبَلْتَهَا عَلَيْهِ) وَإِذَا اِشْتَرَى بَعِيرًا فَلْيَأْخُذْ بِذِرْوَةِ سَنَامِهِ وَلْيَقُلْ مِثْلَ ذَلِكَ

   (when you marry a woman or buy a maidservant, you should say:(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.)
