Mishkat al-Masabih 4 Prayer كتاب الصلاة 661

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ الدِّينَ يُسْرٌ وَلَنْ يُشَادَّ الدِّينَ أَحَدٌ إِلَّا غَلَبَهُ فَسَدِّدُوا وَقَارِبُوا وَأَبْشِرُوا وَاسْتَعِينُوا بِالْغَدْوَةِ وَالرَّوْحَةِ وَشَيْءٍ مِنَ الدُّلْجَةِ» . رَوَاهُ الْبُخَارِيُّ

Abu Huraira reported God’s Messenger as saying, “The religion is ease, but if anyone overdoes it it gets the better of him; so keep to the right course, approximate to perfection, rejoice, and ask help in the morning, the evening, and some of the latter part of the night.” Bukhari transmitted it.
