Sahih al-bukhari:3071 Chapter: The superiority of Jihad Book 56, Hadith 276

Narrated Um Khalid: (the daughter of Khalid bin Sa`id) I went to Allah’s Messenger (ﷺ) with my father and I was Nearing a
yellow shirt. Allah’s Messenger (ﷺ) said, “Sanah, Sanah!” (`Abdullah, the narrator, said that ‘Sanah’ meant
‘good’ in the Ethiopian language). I then started playing with the seal of Prophethood (in between the
Prophet’s shoulders) and my father rebuked me harshly for that. Allah’s Messenger (ﷺ) said. “Leave her,” and
then Allah’s Messenger (ﷺ) (invoked Allah to grant me a long life) by saying (thrice), “Wear this dress till it
is worn out and then wear it till it is worn out, and then wear it till it is worn out.” (The narrator adds,
“It is said that she lived for a long period, wearing that (yellow) dress till its color became dark
because of long wear.”)
