وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَيْسَ صَلَاةً أَثْقَلَ عَلَى الْمُنَافِق مِنَ الْفَجْرِ وَالْعِشَاءِ وَلَوْ يَعْلَمُونَ مَا فِيهِمَا لأتوهما وَلَو حبوا»

He also reported God’s Messenger as saying, "No prayer is more burdensome to the hypocrites than the dawn and the evening prayer; but if they know what blessing lies in them, they would come to them even if they had to crawl to do so.” (Bukhari and Muslim.)
