“It belongs to Zainab. She prays here and when she gets tired she holds on to it.” He said: “Untie it, untie it; let any one of you pray when he has energy, if he gets tired let him sit down.” (Using translation from Ibn Mājah 1371)   

أَنَّ رَسُولَ اللهِ ﷺ دَخَلَ الْمَسْجِدَ وَحَبْلٌ مَمْدُودٌ بَيْنَ سَارِيَتَيْنِ فَقَالَ «مَا هَذَا»؟ قَالُوا زَيْنَبَ فَإِذَا فَتَرَتْ أَوْ كَسِلَتْ تَعَلَّقَتْ بِهِ فَقَالَ رَسُولُ اللهِ ﷺ «لِيَصِلِّ أَحَدُكُمْ نَشَاطَهُ فَإِذَا كَسِلَ أَوْ فَتَرَ فَلْيَقْعُدْ»  

Once the Prophet ﷺ came while a woman was sitting with me. He said, "Who is she?" I replied, "She is so and so," and told him about her (excessive) praying. He said disapprovingly, "Do (good) deeds which is within your capacity (without being overtaxed) as Allah does not get tired (of giving rewards) but (surely) you will get tired and the best deed (act of Worship) in the sight of Allah is that which is done regularly." (Using translation from Bukhārī 43)  

أَنَّ النَّبِيَّ ﷺ دَخَلَ عَلَيْهَا وَعِنْدَهَا امْرَأَةٌ فَقَالَ مِنْ هَذِهِ؟ قَالَتْ فُلَانَةُ لَا تَنَامُ تَذْكُرُ مِنْ صَلَاتِهَا فَقَالَ «مَهْ عَلَيْكُمْ بِمَا تُطِيقُونَ فَوَاللهِ لَا يَمَلُّ اللهُ حَتَّى تَمَلُّوا وَلَكِنْ أَحَبُّ الدِّينِ إِلَيْهِ مَا دَامَ عَلَيْهِ صَاحِبُهُ»
