It was narrated from 'Abdullah bin 'Amr that the Prophet P.B.U.H said: "When anyone of you gets a new wife, a servant, or an animal, let him take hold of the forelock and say: 'Allahumma inni as'aluka min khayriha wa khayri ma jubilat 'alaihi, wa 'audhu bika
min sharriha wa sharri ma jubilat 'alaih (0 Allah, I ask You for the goodness within her and the goodness that she is inclined towards, and I seek refuge with You from the evil within her and the evil to which she is inclined):" (Hasan)
