[Machine] The Messenger of Allah ﷺ saw a rope stretched between two pillars in the mosque, so he asked, "What is this rope?" It was said, "O Messenger of Allah, it is for Hamnah bint Jahsh who prays, and when she becomes fatigued, she holds onto the rope." The Messenger of Allah ﷺ said, "Let her pray as much as she is able, and when she becomes tired, she should sit down." This narration was told to me by Ali, who was told by Ismail, who was told by Abu Nu'aiman, who was told by Hammad ibn Salamah, who heard it from Humaid, who heard it from Anas, with a similar wording. Al-Dhahabi did not mention this in his summary.  

أَنَّ رَسُولَ اللَّهِ ﷺ رَأَى فِي الْمَسْجِدِ حَبْلًا مَمْدُودًا بَيْنَ سَارِيَتَيْنِ فَقَالَ «مَا هَذَا الْحَبْلُ؟» فَقِيلَ يَا رَسُولَ اللَّهِ حَمْنَةُ بِنْتُ جَحْشٍ تُصَلِّي فَإِذَا أَعْيَتْ تَعَلَّقَتْ بِالْحَبَلِ فَقَالَ رَسُولُ اللَّهِ ﷺ «لِتُصَلِّ مَا أَطَاقَتْ فَإِذَا أَعْيَتْ فَلْتَقْعُدْ» وَحَدَّثَنِي عَلِيٌّ ثَنَا إِسْمَاعِيلُ ثَنَا أَبُو النُّعْمَانِ ثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ حُمَيْدٍ عَنْ أَنَسٍ بِمِثْلِهِسكت عنه الذهبي في التلخيص
