Sahih al-Bukhari 5993Book 78, Hadith 24
Um Khalid bint Khalid bin Sa`id said, "I came to Allah's Messenger (ﷺ) along with my father and I was wearing a yellow shirt. Allah's Messenger (ﷺ) said, "Sanah Sanah!" (`Abdullah, the sub-narrator said, "It means, 'Nice, nice!' in the Ethiopian language.") Um Khalid added, "Then I started playing with the seal of Prophethood. My father admonished me. But Allah's Messenger (ﷺ) said (to my father), "Leave her," Allah's Messenger (ﷺ) (then addressing me) said, "May you live so long that your dress gets worn out, and you will mend it many times, and then wear another till it gets worn out (i.e. May Allah prolong your life)." (The sub-narrator, `Abdullah aid, "That garment (which she was wearing remained usable for a long period.").
