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 (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.")

حَدَّثَنَا حِبَّانُ بْنُ مُوسَى، أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ خَالِدِ بْنِ سَعِيدٍ، عَنْ أَبِيهِ، عَنْ أُمِّ خَالِدٍ بِنْتِ خَالِدِ بْنِ سَعِيدٍ، قَالَتْ أَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم مَعَ أَبِي وَعَلَىَّ قَمِيصٌ أَصْفَرُ، قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ سَنَهْ سَنَهْ ‏"‏‏.‏ قَالَ عَبْدُ اللَّهِ وَهْىَ بِالْحَبَشِيَّةِ حَسَنَةٌ‏.‏ قَالَتْ فَذَهَبْتُ أَلْعَبُ بِخَاتَمِ النُّبُوَّةِ، فَزَبَرَنِي أَبِي قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ دَعْهَا ‏"‏‏.‏ ثُمَّ قَالَ رَسُولُ اللَّهِ ‏"‏ أَبْلِي وَأَخْلِفِي، ثُمَّ أَبْلِي وَأَخْلِفِي، ثُمَّ أَبْلِي وَأَخْلِفِي ‏"‏‏.‏ قَالَ عَبْدُ اللَّهِ فَبَقِيَتْ حَتَّى ذَكَرَ‏.‏
