Her name is Rumaysa Bint-e-Milhaan Ansariyah and her Kunyah is Umm-e-Sulaym. She رَضِیَ اللّٰەُ عَنْهَا is the Rada’ee [رَضاعِی] aunt of the beloved father of the Holy Prophet صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, Sayyiduna ‘Abdullah رَضِىَ اللّٰەُ عَنْهُ (Mirat-ul-Manajih, vol. 8, pp. 53), and the mother of the servant of the Holy Prophet صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, Sayyiduna Anas Bin Maalik رَضِىَ اللّٰەُ عَنْهُ. She رَضِیَ اللّٰەُ عَنْهَا belonged to the tribe of Banu Najjaar. She رَضِیَ اللّٰەُ عَنْهَا was blessed with embracing Islam and performing Bay’at.
Marriage and children
Her first marriage was with Maalik Bin Nadr. From this marriage, she رَضِیَ اللّٰەُ عَنْهَا gave birth to Sayyiduna Anas and Sayyiduna Bara رَضِىَ اللّٰەُ عَنْهُمَا. When Allah Almighty blessed her with the treasure of Iman, then she رَضِیَ اللّٰەُ عَنْهَا also invited her husband towards Islam but he did not accept her invitation. Furious, he left for Syria and passed away there. After the death of Maalik Bin Nadr, she رَضِیَ اللّٰەُ عَنْهَا was married to Sayyiduna Abu Talhah Ansari رَضِىَ اللّٰەُ عَنْهُ. From this marriage, she رَضِیَ اللّٰەُ عَنْهَا gave birth to Sayyiduna ‘Abdullah and Sayyiduna Abu ‘Umayr رَضِىَ اللّٰەُ عَنْهُمَا.

Few glimpses of her observance of reverence towards the Holy Rasool ﷺ
٭ One day, the Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم came to the house of Sayyidatuna Umm-e-Sulaym رَضِیَ اللّٰەُ عَنْهَا and drank water from a vessel. Sayyidatuna Umm-e-Sulaym رَضِیَ اللّٰەُ عَنْهَا cut that piece off where the Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم drank water from and kept it as a sacred relic. (Musnad Ahmad, vol. 10, pp. 319, Hadees 27185)
٭ The Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم would come to her and perform Qaylulah there. She رَضِیَ اللّٰەُ عَنْهَا used to lay down the bedding of leather for the Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم. The Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم used to rest upon it. The Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم would perspire a lot. She رَضِیَ اللّٰەُ عَنْهَا would gather the [blessed] perspiration of the Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم and mix it in the fragrance. Once, the Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم woke up and said, ‘O Umm-e-Sulaym! What are you doing?’ She humbly replied, ‘Huzoor! This is your [blessed] perspiration which we mix in our fragrance. This is an excellent fragrance.’ In another narration, it is stated that she رَضِیَ اللّٰەُ عَنْهَا humbly replied, ‘Ya Rasoolallah صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم! We hope for its blessings for our children.’ He صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم replied, ‘You do right.’ Therefore, when the time of the demise of Sayyiduna Anas رَضِىَ اللّٰەُ عَنْهُ approached, he رَضِىَ اللّٰەُ عَنْهُ left a will saying that this fragrance be mixed in his ‘Hanoot’. Therefore, as per his will, that fragrance was mixed in the Hanoot of Sayyiduna Anas Bin Maalik رَضِىَ اللّٰەُ عَنْهُ. (Sahih Bukhari, vol. 4, pp. 182, Hadees 6281; Sahih Muslim, pp. 978, 979, Hadees 6055-6057; Musnad Ahmad, vol. 4, pp. 451, Hadees 13365)
Saw in the Paradise
The Holy Rasool صَلَّى اللّٰەُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم states, ‘In a dream, I saw myself to be in the Paradise. All of a sudden, I saw the wife of Abu Talhah, Rumaysa, in the Paradise.’ (Sahih Bukhari, vol. 2, pp. 525, Hadees 3679)
Services rendered to Ahadees
The illustrious and dignified personalities like Sayyiduna Anas Bin Maalik, Sayyiduna ‘Abdullah Bin ‘Abbas, Sayyiduna ‘Amr Bin ‘Aasim Ansari and Abu Salamah Bin ‘Abdur Rahman رَضِىَ اللّٰەُ عَنْهُم narrated Ahadees from her. Moreover, Ahadees narrated by her have been narrated in Sahih Bukhari, Sahih Muslim, Abu Dawood, Sunan-ut-Tirmizi and Sunan Nasa`ee. (Tahzeeb-ut-Tahzeeb, vol. 10, pp. 522, 523)
Her year of death has not been mentioned in the books of Seerah. However, ‘Allamah Ibn Hajar ‘Asqalani رَحْمَةُ اللّٰەِ عَلَيْه has written that she رَضِیَ اللّٰەُ عَنْهَا passed away during the caliphate of Sayyiduna Usman-e-Ghani رَضِىَ اللّٰەُ عَنْهُ. (Taqreeb-ut-Tahzeeb, pp. 1381)
May Allah Almighty shower His mercy upon her and forgive us without accountability for her sake!
