Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، وَعَبْدُ بْنُ حُمَيْدٍ، جَمِيعًا عَنْ عَبْدِ الرَّزَّاقِ، عَنِ ابْنِ جُرَيْجٍ، بِهَذَا الإِسْنَادِ وَزَادَ قَالَ عَطَاءٌ كَانَتْ آخِرَهُنَّ مَوْتًا مَاتَتْ بِالْمَدِينَةِ
Translation

Ibn Juraij narrated a hadith with the same chain of transmitters, and she (Hadrat Maimuna) was the last of them to die at Medina.
