Remembrance 2 from Chapter 229
What the groom should say when his bride comes to him on the wedding night
Allāhumma innī as’aluka khayrahā wa khayra mā jabaltahā ‘alayh, wa a‘ūdhu bika min sharrihā wa sharri mā jabaltahā ‘alayh.
And to say together with it that which we relate, with ṣaḥīḥ isnāds, from the Sunans of Abū Dāwūd and Ibn Mājah, that ‘Amr ibn Shu‘ayb reported from his father, who reported that his grandfather related that the Messenger of Allah 
said: “If any of you marries a woman or buys a slavegirl, he should say: ‘O Allah, I ask for the good in her and the good that You have created in her, and I seek Your protection from her evil and the evil that You have created in her.” [1].If he buys a camel he should take hold of the top of its hump and say the same. According to another report he said: “Then he should take hold of her forelock and say a du‘ā’ for blessing in the woman or the slavegirl.” [2].
