Sawdah bint Zam’ah
Sawdah bint Zamʿah (Arabic: سودة بنت زمعة transliterations include Sawda bint Zam'a) was a widow who managed the affairs of the Prophet's (ﷺ) household. She took care of Umm Kulthoom and Fatimah and eventually married the Prophet (ﷺ) making her on of the Mother of the Believers.
Sawdah was a humours women very dark in complexion, and slow moving due to been quite overweight.
After the death of Khadijah bint Khuwaylid the Messenger of Allah (ﷺ) was approached by Khawlah bint Hakim. She was aware of his loneliness and suggested he remarry by taking a matron and a virgin to fulfil the needs of his heart and household. Sawdah was suggested as the matron to help the Prophet (ﷺ) run the household and the virgin was Aisha bint Abdallah ibn Abi Quḥafah to help mend his broken heart.
Fear of Divorce
Sawdah being older and not as healthy began to feel she was becoming a liability to the Prophet (ﷺ) and his family so she requested that she remain married and would relinquish her time to her best friend Aisha.
Sawdah's death was prophesied by the Messenger of Allah (ﷺ). He was asked who amongst his wives would be the first to follow him to which he replied, "The one with the longest arms." Believing this to be a literal statement they began to measure their arms with a stick not realizing the true meaning was the one who gave the most in charity.

Chapters on Hajj Rituals
It was narrated from ‘Aishah that Sawdah bint Zam’ah was a slow-moving woman, so she asked the Messenger of Allah (ﷺ) for permission to depart from Jam’ ahead of the people, and he gave her permission.
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ سَوْدَةَ بِنْتَ زَمْعَةَ، كَانَتِ امْرَأَةً ثَبِطَةً فَاسْتَأْذَنَتْ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أَنْ تَدْفَعَ مِنْ جَمْعٍ قَبْلَ دُفْعَةِ النَّاسِ فَأَذِنَ لَهَا
The Book of Hajj
It was narrated that Aishah said: "The Prophet allowed Sawdah to leave Jam (Al-Muzdalifah) before dawn because she was a heavyset woman.
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا هُشَيْمٌ، قَالَ أَنْبَأَنَا مَنْصُورٌ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، قَالَتْ إِنَّمَا أَذِنَ النَّبِيُّ صلى الله عليه وسلم لِسَوْدَةَ فِي الإِفَاضَةِ قَبْلَ الصُّبْحِ مِنْ جَمْعٍ لأَنَّهَا كَانَتِ امْرَأَةً ثَبِطَةً
Chapter: The Skin Of Dead Animals (Those Not Slaughtered Or Killed Properly)
It was narrated that Sawdah, the wife of the Prophet, said:"A sheep of ours died, and we tanned its skin, and continued to make Nabidh in it until it wore out." 
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ بْنِ أَبِي رِزْمَةَ، قَالَ أَنْبَأَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، عَنِ الشَّعْبِيِّ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، عَنْ سَوْدَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم قَالَتْ مَاتَتْ شَاةٌ لَنَا فَدَبَغْنَا مَسْكَهَا فَمَازِلْنَا نَنْبِذُ فِيهَا حَتَّى صَارَتْ شَنًّا
Chapter: The Book of Zakah
It was narrated from 'Aishah, may Allah be pleased with her, that the wives of the Prophet "gathered around him and said: "Which of us will be the first to following you (in death)?" He said: "The one of you who has the longest arms." They took a stick and started to measure their arms. But Sawdah was the first one to follow him. She was the one who had the longest arms, because she used to give in charity a great deal.
أَخْبَرَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا يَحْيَى بْنُ حَمَّادٍ، قَالَ أَنْبَأَنَا أَبُو عَوَانَةَ، عَنْ فِرَاسٍ، عَنْ عَامِرٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، رضى الله عنها أَنَّ أَزْوَاجَ، النَّبِيِّ صلى الله عليه وسلم اجْتَمَعْنَ عِنْدَهُ فَقُلْنَ أَيَّتُنَا بِكَ أَسْرَعُ لُحُوقًا فَقَالَ " أَطْوَلُكُنَّ يَدًا " . فَأَخَذْنَ قَصَبَةً فَجَعَلْنَ يَذْرَعْنَهَا فَكَانَتْ سَوْدَةُ أَسْرَعَهُنَّ بِهِ لُحُوقًا فَكَانَتْ أَطْوَلَهُنَّ يَدًا فَكَانَ ذَلِكَ مِنْ كَثْرَةِ الصَّدَقَةِ
Chapters on Tafsir
Narrated Ibn 'Abbas: "Sawdah feared that the Prophet (ﷺ) was going to divorce her, so she said: 'Do not divorce me, but keep me and give my day to 'Aishah.' So he (ﷺ) did so, and the following was revealed: Then there is no sin on them both if they make terms of peace between themselves, and making peace is better (4:128). So whatever they agree to make peace in something then it is permissible." 
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ، حَدَّثَنَا سُلَيْمَانُ بْنُ مُعَاذٍ، عَنْ سِمَاكٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ خَشِيَتْ سَوْدَةُ أَنْ يُطَلِّقَهَا، النَّبِيُّ صلى الله عليه وسلم فَقَالَتْ لاَ تُطَلِّقْنِي وَأَمْسِكْنِي وَاجْعَلْ يَوْمِي لِعَائِشَةَ فَفَعَلَ فَنَزَلَتْ : ( فَلاَ جُنَاحَ عَلَيْهِمَا أَنْ يُصْلِحَا بَيْنَهُمَا صُلْحًا وَالصُّلْحُ خَيْرٌ ) . فَمَا اصْطَلَحَا عَلَيْهِ مِنْ شَيْءٍ فَهُوَ جَائِزٌ كَأَنَّهُ مِنْ قَوْلِ ابْنِ عَبَّاسٍ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ
