Narrator:Anas ibn Mālik
حَدَّثَنَا أَبُو مَعْمَرٍ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ دَخَلَ النَّبِيُّ صلى الله عليه وسلم فَإِذَا حَبْلٌ مَمْدُودٌ بَيْنَ السَّارِيَتَيْنِ فَقَالَ " مَا هَذَا الْحَبْلُ ". قَالُوا هَذَا حَبْلٌ لِزَيْنَبَ فَإِذَا فَتَرَتْ تَعَلَّقَتْ. فَقَالَ النَّبِيُّ صلى الله عليه وسلم "
لاَ، حُلُّوهُ، لِيُصَلِّ أَحَدُكُمْ نَشَاطَهُ، فَإِذَا فَتَرَ فَلْيَقْعُدْ "
Anas (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) came one day into the mosque and saw a rope stretched between two poles. He inquired: "What is this rope for?" He was told: "This is Zaynab's rope. When she feels tired (in voluntary prayer), she holds on to it for support." The Prophet (may Allah's peace and blessings be upon him) said: "Untie it. You should pray as long as you have the energy to do so. If you feel tired, then lie down."
