Supplication when getting married or acquiring a servant or animal

The Prophet ﷺ said: "When any of you marries or acquires a servant, let him say:"

"O Allah, I ask You for the good in her and the good in the nature You have created her upon, and I seek refuge in You from the evil in her and from the evil in the nature You have created her upon."

When buying a camel, one should grasp the top of its hump and recite the same words (for a male camel, switch the pronouns to the masculine form — «-hu» instead of «-ha»).

[Abu Dawud 2160; Sahih al-Jami‘ 341]
