Supplication on marrying or buying a riding animal

Reading settings
دُعَاءُ الْمُتَزَوِّجِ لِنَفْسِهِ
اللَّهُمَّ إِنِّي أَسْأَلُكَ خَيْرَهَا وَخَيْرَ مَا جَبَلْتَهَا عَلَيْهِ وَأَعُوذُ بِكَ مِنْ شَرِّهَا وَشَرِّ مَا جَبَلْتَهَا عَلَيْهِ ، وَإِذَا اشْتَرَى بَعِيرًا فَلْيَأْخُذْ بِذُرْوَةِ سَنَامِهِ وَلْيَقُلْ مِثْلَ ذَلِكَ
A newly married person's supplication

O Allah, I ask You for her good and the good nature You created in her, and I seek refuge in You from her evil and the evil nature You created in her. When buying a camel, take hold of the top of its hump and say the same.
