[Machine] The Messenger of Allah, ﷺ , said, "Fasting the month of Ramadan is equivalent to ten months of fasting, and fasting six days of Shawwal is equivalent to two months. That is fasting for a year."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «صِيَامُ شَهْرِ رَمَضَانَ بِعَشَرَةِ أَشْهُرٍ وَصِيَامُ سِتَّةِ أَيَّامٍ مِنْ شَوَّالٍ بِشَهْرَيْنِ فَذَلِكَ صِيَامُ سَنَةٍ»
[Machine] On the authority of Thawban, the servant of the Messenger of Allah ﷺ , that the Messenger of Allah ﷺ said, "Fasting for one month with ten days added to it, followed by two months of fasting, completes the year. That is, fasting in Ramadan and six days after it."
عَنْ ثَوْبَانَ مَوْلَى رَسُولِ اللهِ ﷺ أَنَّ رَسُولَ اللهِ ﷺ قَالَ صِيَامُ شَهْرٍ بِعَشَرَةِ أَشْهُرٍ وَسِتَّةِ أَيَّامٍ بَعْدَهُ بِشَهْرَيْنِ فَذَلِكَ تَمَامُ السَّنَةِ يَعْنِي رَمَضَانَ وَسِتَّةَ أَيَّامٍ بَعْدَهُ
"صِيَامُ شَهْرِ رَمَضَانَ بِعَشْرَة أشْهَرٍ، وَصِيَامُ سِتَّةِ أَيَّامٍ، بشَهْرَين، بَعْدَ الْفِطْرِ، فَذَلِكَ صِيَامُ السَّنَةِ".
