Al-Kāfi|Volume 3|Book 4|Chapter 84
21ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ عَنِ ابْنِ بُكَيْرٍ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) مَا كَانَ يُحْمَدُ الرَّجُلُ أَنْ يَقُومَ مِنْ آخِرِ اللَّيْلِ فَيُصَلِّيَ صَلاَتَهُ ضَرْبَةً وَاحِدَةً ثُمَّ يَنَامَ وَيَذْهَبَ.
21. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan from ibn Bukayr who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘A man who gets up in the end of the night to perform his nightly optional Salah (prayer), all of them at one time and goes away to sleep, is not very praiseworthy.”
