I heard the Messenger of Allah ﷺ say: Keeping watch for a day and a night is better (in point of reward) than fasting for a whole month and standing in prayer every night. If a person dies (while, performing this duty), his (meritorious) activity will continue and he will go on receiving his reward for it perpetually and will be saved from the torture of the grave.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ رِبَاطُ يَوْمٍ وَلَيْلَةٍ خَيْرٌ مِنْ صِيَامِ شَهْرٍ وَقِيَامِهِ وَإِنْ مَاتَ جَرَى عَلَيْهِ عَمَلُهُ الَّذِي كَانَ يَعْمَلُهُ وَأُجْرِيَ عَلَيْهِ رِزْقُهُ وَأَمِنَ الْفَتَّانَ  

"I heard the Messenger of Allah ﷺ say: 'Whoever guards Ribat (the frontier) in the cause of Allah for one day and one night, he will have (a reward) like that of fasting and praying Qiyam for a month. If he dies he will continue to receive reward for what he did, and he will be kept safe from Al-Fattan, and he will be given provision.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ رَابَطَ فِي سَبِيلِ اللَّهِ يَوْمًا وَلَيْلَةً كَانَتْ لَهُ كَصِيَامِ شَهْرٍ وَقِيَامِهِ فَإِنْ مَاتَ جَرَى عَلَيْهِ عَمَلُهُ الَّذِي كَانَ يَعْمَلُ وَأَمِنَ الْفَتَّانَ وَأُجْرِيَ عَلَيْهِ رِزْقُهُ  

[Machine] He heard the Messenger of Allah ﷺ saying, "The reward of spending a day and night in the cause of Allah is like the reward of fasting and praying for a month. If a person dies in this state, they will continue to receive the reward of being steadfast until they are resurrected and protected from temptation."  

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ رِبَاطُ يَوْمٍ وَلَيْلَةٍ فِي سَبِيلِ اللهِ كَصِيَامِ شَهْرٍ وَقِيَامِهِ إِنْ مَاتَ جَرَى عَلَيْهِ أَجْرُ الْمُرَابِطِ حَتَّى يُبْعَثَ وَيُؤْمَنَ الْفَتَّانَ  

"Whoever guards Ribat (the frontier) for one day and one night, will be given a reward like that for fasting and praying Qiyam for a month, and whoever dies at Ribat (guarding the frontier) will be rewarded, and he will be given provision, and he will be kept safe from Al-Fattan." [1] [1] According to As-Sindi, the preferred pronunciation is Al-Fattan, plural of Fatan refering to Al-Munkar and An-Nakir, while Al-Fattan would refer to Ash-Shaitan or the like, among the punishment of the grave, or, the angels of chastisement. (Using translation from Nasāʾī 3167)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ رَابَطَ يَوْمًا وَلَيْلَةً فِي سَبِيلِ اللَّهِ كَانَ لَهُ أَجْرُ صِيَامِ شَهْرٍ وَقِيَامِهِ وَمَنْ مَاتَ مُرَابِطًا جَرَى لَهُ مِثْلُ ذَلِكَ الْأَجْرِ وَأَجْرَى عَلَيْهِ الرِّزْقَ وَأُومِنَ مِنَ الْفَتَّانَ»  

I heard the Messenger of Allah ﷺ say: Keeping watch for a day and a night is better (in point of reward) than fasting for a whole month and standing in prayer every night. If a person dies (while, performing this duty), his (meritorious) activity will continue and he will go on receiving his reward for it perpetually and will be saved from the torture of the grave. (Using translation from Muslim 1913a)   

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «مَنْ مَاتَ مُرَابِطًا أُجْرِيَ عَلَيْهِ عَمَلُهُ الَّذِي كَانَ يَعْمَلُ وَأُومِنَ الْفَتَّانَ وَيَجْرِي عَلَيْهِ رِزْقُهُ»  

[Machine] "Shall I not guide you to something that will be of great benefit to you?" The Messenger of Allah ﷺ said, "A day spent in the way of Allah is better than fasting and praying all night for a month. And whoever dies while actively engaged in the cause of Allah, his deeds will continue to be rewarded, and he will be protected from the trials of the grave."  

لَهُ أَلَا أُرَغِّبَنَّكَ فِيمَا أَنْتَ فِيهِ؟ قَالَ رَسُولُ اللهِ ﷺ «رِبَاطُ يَوْمٍ فِي سَبِيلِ اللهِ خَيْرٌ مِنْ صِيَامِ شَهْرٍ وَقِيَامِهِ وَمَنْ مَاتَ مُرَابِطًا فِي سَبِيلِ اللهِ جَرَى لَهُ عَمَلُهُ أَوْ أَعْمَالُهُ وَوُقِيَ فِتْنَةَ الْقَبْرِ»  

[Machine] The Messenger of Allah ﷺ said, "The devotion of one day and one night is better than fasting for a whole month and praying during that month. And whoever dies while defending the cause of Allah will receive the same reward, and his sustenance will continue, and he will be protected from the punishment of the grave."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «رِبَاطُ يَوْمٍ وَلَيْلَةٍ أَفْضَلُ مِنْ صِيَامِ شَهْرٍ وَقِيَامِهِ وَمَنْ مَاتَ مُرَابِطًا فِي سَبِيلِ اللهِ جَرَى عَلَيْهِ مِثْلُ ذَلِكَ فِي الثَّوَابِ وَأُجْرِيَ عَلَيْهِ رِزْقُهُ وَأُومِنَ الْفَتَّانَ»  

[Machine] He saw Salman Al-Farisi while he was guarding the coast of Homs. He asked, "What brings you here?" Salman replied, "I am guarding." Salman said, "I heard the Messenger of Allah ﷺ say, 'A day guarding for the sake of Allah is equivalent to fasting and praying for a month. And whoever dies while guarding, his deeds will continue and he will be protected from the trials, and he will be resurrected on the Day of Judgment as a martyr.'"  

أَنَّهُ رَأَى سَلْمَانَ الْفَارِسِيَّ وَهُوَ مُرَابِطٌ بِسَاحِلِ حِمْصٍ فَقَالَ مَا لَكَ عَلَى هَذَا؟ قَالَ مُرَابِطٌ قَالَ سَلْمَانُ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «رِبَاطُ يَوْمٍ فِي سَبِيلِ اللهِ كَصِيَامِ شَهْرٍ وَقِيَامِهِ وَمَنْ مَاتَ مُرَابِطًا جَرَى عَلَيْهِ عَمَلُهُ الَّذِي كَانَ يَعْمَلُ وَأُومِنَ الْفَتَّانَ وَيُبْعَثُ يَوْمَ الْقِيَامَةِ شَهِيدًا»  

[Machine] That Salman passed by him while he was stationed in the land of Fars and said, "Shall I inform you of something that will be of assistance to you in guarding your post?" He replied, "Yes." He said, "I heard the Messenger of Allah ﷺ say, 'Guarding a post for one day in the cause of Allah is better than fasting and praying for a month.'"  

أَنَّ سَلْمَانَ مَرَّ بِهِ وَهُوَ مُرَابِطٌ بِأَرْضِ فَارِسَ فَقَالَ أَلَا أُخْبِرُكَ بِأَمْرٍ يَكُونُ لَكَ عَوْنًا عَلَى رِباطِكَ؟ قَالَ بَلَى قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «رِبَاطُ يَوْمٍ فِي سَبِيلِ اللهِ خَيْرٌ مِنْ صِيَامِ شَهْرٍ وَقِيَامِهِ»  

"رباط يوْمٍ ولَيْلَةٍ خَيْرٌ منْ صيامِ شَهْرٍ وقيامه، وَإِنْ مات مُرابطًا جرى علَيْه عملُهُ الَّذى كَانَ يعْملُهُ، وأُجرى علَيْه رزْقُهُ وأَمنَ منَ الفتن".  

"رباطُ يوْمٍ ولَيْلَة فِى سبيلِ اللَّهِ خَيْرٌ مِنْ صِيامِ شَهْرٍ وقِيامِهِ، فإِن مات جرى علَيْهِ أَجْرُ الرابطِ ومُؤْمَّن مِنَ الفَتَّان، ويُقْطَعُ لَهُ رزْقٌ مِن الجنَّةِ".  

"رباطُ يوْمٍ فِى سبيل اللَّهِ أَفْضَلُ مِنْ صِيامَ شَهْرٍ وقِيامِهِ، ومنْ مات مُرابطًا فِى سِبيلِ اللَّهِ أُجيرِ مِنْ فِتنةِ القَبْر، ويجْرِى لَهُ صالِحُ ما كان يعْملُ إِلى يوْمِ القِيامةِ".  

"رِباطُ يوْمٍ فِى سبيلِ اللَّهِ كَصِيامِ شَهْرٍ وقِيامِهِ، ومْنِ ماتَ مُرَابِطًا جَرَى عَلَيْهِ عَمَلُهُ الَّذِى كَانَ يَعْمَلُ، وَأُومِنَ الفَتَّانَ، وَيُبْعَثُ يَوْمَ القِيَامَةِ شَهِيدًا".  

"مَنْ رَابَطَ يَوْمًا وَلَيلَةً في سَبِيلِ اللهِ كَانَ لَهُ كَأَجْرِ صِيَامِ شَهْرٍ وَقِيَامِهِ، [وَمَنْ مَاتَ مُرَابِطًا جَرَى لَهُ مثلُ ذَلِكَ مِنَ الأَجْرِ] وَأُجْرِي عَلَيهِ الرِّزْق وَأَمِنَ الفَتَّان".  

"مَنْ مَاتَ مُرَابطًا في سَبِيلِ الله، أُجِيرَ مِنْ فِتْنَةِ الْقَبْرِ، وَجَرَى عَلَيهِ صَالِحُ عَمَلِهِ الَّذِي كَانَ يَعْمَلُ إِلَى يَوْمِ الْقِيَامَةِ".
