"The Messenger of Allah said: 'The most burdensome prayers for the hypocrites are the 'Isha' prayer and the Fajr prayer. If only they knew what (reward) there is in them, they would come to them even if they had to crawl.'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ أَثْقَلَ الصَّلاَةِ عَلَى الْمُنَافِقِينَ صَلاَةُ الْعِشَاءِ وَصَلاَةُ الْفَجْرِ وَلَوْ يَعْلَمُونَ مَا فِيهِمَا لأَتَوْهُمَا وَلَوْ حَبْوًا  

"The Messenger of Allah said: 'The most burdensome prayers for the hypocrites are the 'Isha' prayer and the Fajr prayer. If only they knew what (reward) there is in them, they would come to them even if they had to crawl.'" (Using translation from Ibn Mājah 797)  

قَالَ رَسُولُ اللهِ ﷺ إِنَّ أَثْقَلَ الصَّلَاةِ عَلَى الْمُنَافِقِينَ صَلَاةُ الْعِشَاءِ وَالْفَجْرِ وَلَوْ يَعْلَمُونَ مَا فِيهِمَا لَأَتَوْهُمَا وَلَوْ حَبْوًا  

[Machine] The messenger of Allah, ﷺ , said: "No prayer is heavier upon the hypocrites than the prayer of Isha and Fajr, and if they knew the reward they have in them, they would attend them even if crawling."  

قَالَ رَسُولُ اللهِ ﷺ «مَا صَلَاةٌ أَثْقَلَ عَلَى الْمُنَافِقِينَ مِنْ صَلَاةِ الْعِشَاءِ وَالْفَجْرِ وَلَوْ يَعْلَمُونَ مَا فِيهِمَا مِنَ الْفَضْلِ لَأَتَوْهُمَا وَلَوْ حَبْوًا»  

"إِنّ أَثقلَ الصلاةِ على المنافقين صلاةُ العشاءِ والفجرِ، ولو عَلِموا ما فِيهمَا من الفضل لأَتَوْهُما ولو حَبْوًا".
