Tahdhīb al-Aḥkām|Volume 4|Book 2|Chapter 7
وَ عَنْهُ عَنْ عَلِيٍّ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:» نَوْمُ اَلصَّائِمِ عِبَادَةٌ وَ نَفَسُهُ تَسْبِيحٌ«.
And from him, from Ali, from Harun ibn Muslim, from Masadah, from Abu Abdillah عليه السلام, peace be upon him, who said:
Imam عليه السلام said: “The sleep of the fasting person is worship, and his breath is glorification.”
