[Machine] The Messenger of Allah ﷺ prayed Fajr prayer with us, and when he finished his prayer, he turned towards us with his face and said, "Indeed, the heaviest prayers on the hypocrites are these two prayers."  

صَلَّى بِنَا رَسُولُ اللهِ ﷺ صَلَاةَ الصُّبْحِ فَلَمَّا قَضَى صَلَاتَهُ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ ثُمَّ قَالَ إِنَّ أَثْقَلَ الصَّلَوَاتِ عَلَى الْمُنَافِقِينَ هَاتَانِ الصَّلَاتَانِ  

[Machine] The Messenger of Allah ﷺ prayed the Fajr prayer and then asked, "Is so-and-so present?" For a group of hypocrites who did not attend the prayer. Then he said, "Indeed, these two prayers are the heaviest prayers on the hypocrites. If they knew the reward that these prayers contain, they would have come to them, even if they had to crawl." He means the Isha prayer and the Fajr prayer.  

صَلَّى رَسُولُ اللَّهِ ﷺ صَلَاةَ الصُّبْحِ فَقَالَ «أَشَاهِدٌ فُلَانٌ؟» لِنَفَرٍ مِنَ الْمُنَافِقِينَ لَمْ يَشْهَدُوا الصَّلَاةَ ثُمَّ قَالَ «إِنَّ هَاتَيْنِ الصَّلَاتَيْنِ مِنْ أَثْقَلِ الصَّلَوَاتِ عَلَى الْمُنَافِقِينَ وَلَوْ يَعْلَمُونَ مَا فِيهِمَا لَأَتَوْهُمَا وَلَوْ حَبْوًا» يَعْنِي صَلَاةَ الْعِشَاءِ وَالصُّبْحَ  

The Messenger of Allah ﷺ led us in the dawn prayer one day. And he said: Is so and so present? They said: No. He (again) asked: Is so and so present? They replied: No. He then said: These two prayers are the ones which are most burdensome to hypocrites. If you knew what they contain (i.e. blessings), you would come to them, even though you had to crawl on your knees. The first row is like that of the angels, and if you knew the nature of its excellence, you would race to join it. A man's prayer said along with another is purer than his prayer said alone, and his prayer with two men is purer than his prayer with one, but if there are more it is more pleasing to Allah, the Almighty, the Majestic. (Using translation from Abū Dāʾūd 554)   

صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ الصُّبْحَ فَقَالَ «أَشَاهِدٌ فُلَانٌ؟ » قَالُوا لَا فَقَالَ «أَشَاهِدٌ فُلَانٌ؟ » قَالُوا لَا قَالَ «إِنَّ هَاتَيْنِ الصَّلَاتَيْنِ أَثْقَلُ الصَّلَوَاتِ عَلَى الْمُنَافِقِينَ وَلَوْ يَعْلَمُونَ فَضْلَ مَا فِيهِمَا لَأَتَوْهُمَا وَلَوْ حَبْوًا وَإِنَّ الصَّفَّ الْأَوَّلَ لَعَلَى مِثْلِ صَفِّ الْمَلَائِكَةِ وَلَوْ تَعْلَمُونَ فَضِيلَتَهُ لَابْتَدَرْتُمُوهُ وَصَلَاةُ الرَّجُلِ مَعَ الرَّجُلَيْنِ أَزْكَى مِنْ صَلَاتِهِ مَعَ رَجُلٍ وَكُلَّمَا كَثُرَ فَهُوَ أَحَبُّ إِلَى اللَّهِ»
