From Sahih Bukhari (Hadith 5256):
Narrated Sahl and Abu Usaid:The Prophet (ﷺ) married Umaima bint Sharahil, and when she was brought to him, he stretched his hand towards her. It seemed that she disliked that, whereupon the Prophet (ﷺ) ordered Abu Usaid to prepare her and to provide her with two white linen dresses
