*First Hadīth Of The Day*

حَدَّثَنَا  إِسْحَاقُ بْنُ نَصْرٍ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ أَبِي حَيَّانَ،  عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ  النَّبِيَّ صلى الله عليه وسلم قَالَ لِبِلاَلٍ عِنْدَ صَلاَةِ الْفَجْرِ ‏"‏ يَا بِلاَلُ حَدِّثْنِي  بِأَرْجَى عَمَلٍ عَمِلْتَهُ فِي الإِسْلاَمِ، فَإِنِّي سَمِعْتُ دَفَّ  نَعْلَيْكَ بَيْنَ يَدَىَّ فِي الْجَنَّةِ ‏"
‏‏.‏  قَالَ مَا عَمِلْتُ عَمَلاً أَرْجَى عِنْدِي أَنِّي لَمْ أَتَطَهَّرْ  طُهُورًا فِي سَاعَةِ لَيْلٍ أَوْ نَهَارٍ إِلاَّ صَلَّيْتُ بِذَلِكَ  الطُّهُورِ مَا كُتِبَ لِي أَنْ أُصَلِّيَ‏.‏ قَالَ أَبُو عَبْدِ اللَّهِ  دَفَّ نَعْلَيْكَ يَعْنِي تَحْرِيكَ‏.‏

 Narrated Abu Huraira:                        At the time of the Fajr prayer the Prophet (ﷺ) asked Bilal, "Tell me of the best deed you did after  embracing Islam, for I heard your footsteps in front of me in Paradise." Bilal replied, "I did not do  anything worth mentioning except that whenever I performed ablution during the day or night, I  prayed after that ablution as much as was written for me."

*Second Hadīth Of The Day*

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  ‏"‏‏.‏

 Narrated Anas bin Malik Once the Prophet (p.b.u.h) entered the Mosque and saw a rope hanging in between its two pillars. He said, "What is this rope?" The people said, "This rope is for Zainab who, when she feels tired, holds it (to keep standing for the prayer.)" The Prophet (ﷺ) said, "Don't use it. Remove the rope. You should pray as long as you feel active, and when you get tired, sit down."

*Third Hadīth Of The Day*

قَالَ وَقَالَ عَبْدُ اللَّهِ  بْنِ مَسْلَمَةَ عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ،  عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَتْ عِنْدِي امْرَأَةٌ مِنْ  بَنِي أَسَدٍ فَدَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ  ‏"‏ مَنْ هَذِهِ ‏"‏‏.‏ قُلْتُ فُلاَنَةُ لاَ تَنَامُ بِاللَّيْلِ‏.‏  فَذُكِرَ مِنْ صَلاَتِهَا فَقَالَ ‏"‏ مَهْ عَلَيْكُمْ مَا تُطِيقُونَ مِنَ  الأَعْمَالِ، فَإِنَّ اللَّهَ لاَ يَمَلُّ حَتَّى تَمَلُّوا ‏"‏‏.‏

 Narrated 'Aisha:                             
A woman from the tribe of Bani Asad was sitting with me and Allah's Apostle (p.b.u.h) came to my house and said, "Who is this?" I said, "(She is) So and so. She does not sleep at night because she is engaged in prayer." The Prophet (ﷺ) said disapprovingly: Do (good) deeds which is within your capacity as Allah never gets tired of giving rewards till you get tired of doing good deeds."
