(حديث مرفوع) حَدَّثَنَا مُعَاذُ بْنُ مُعَاذٍ ، حَدَّثَنَا حُمَيْدٌ الطَّوِيلُ ، وَابْنُ أَبِي عَدِيٍّ ، عَنْ حُمَيْدٍ الطَّوِيلِ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، أَنّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ الْمَسْجِدَ فَرَأَى حَبْلًا مَمْدُودًا بَيْنَ سَارِيَتَيْنِ ، قَالَ ابْنُ أَبِي عَدِيٍّ فِي الْمَسْجِدِ ، فَسَأَلَ عَنْهُ ، فَقَالُوا : فُلَانَةُ تُصَلِّي ، فَإِذَا غُلِبَتْ تَعَلَّقَتْ بِهِ ، فَقَالَ : " لِتُصَلِّ مَا عَقَلَتْ ، فَإِذَا غُلِبَتْ فَلْتَنَمْ " .
It is narrated from Hazrat Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) once entered the mosque and saw a rope hanging between two pillars. He asked, "What is this rope?" The people replied, "This is the rope of such-and-such woman; when she feels lazy or tired while praying, she ties herself to it." The Prophet (peace and blessings be upon him) said, "Untie it." Then he said, "When any one of you prays, he should pray as long as he remains energetic, and when he feels lazy or tired, he should stop."
