باب مِنْ فَضَائِلِ زَيْنَبَ أُمِّ الْمُؤْمِنِينَ رضى الله عنها ‏‏
Sahih Muslim 2452

'A'isha, the Mother of the Faithful, reported that Allah's Messenger (ﷺ) said:

One who has the longest hands amongst you would meet me most immediately. She farther said: They (the wives of Allah's Apostle) used to measure the hands as to whose hand was the longest and it was the hand of Zainab that was the longest amongst them, as she used to work with her hand and Spend (that income) on charity.
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ أَبُو أَحْمَدَ، حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى السِّيْنَانِيُّ، أَخْبَرَنَا طَلْحَةُ بْنُ يَحْيَى بْنِ طَلْحَةَ، عَنْ عَائِشَةَ بِنْتِ طَلْحَةَ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ أَسْرَعُكُنَّ لَحَاقًا بِي أَطْوَلُكُنَّ يَدًا ‏"‏ ‏.‏ قَالَتْ فَكُنَّ يَتَطَاوَلْنَ أَيَّتُهُنَّ أَطْوَلُ يَدًا ‏.‏ قَالَتْ فَكَانَتْ أَطْوَلَنَا يَدًا زَيْنَبُ لأَنَّهَا كَانَتْ تَعْمَلُ بِيَدِهَا وَتَصَدَّقُ ‏.‏
