اللَّهُمَّ تَقَبَّلْ مِنَّا رَمَضَانَ وَأَعِنَّا عَلَى صِيَامِ سِتٍّ مِنْ شَوَّالٍ
Allahumma taqabbal minna Ramadan wa a'inna 'ala siyami sittin min Shawwal
O Allah, accept our Ramadan and help us fast six days of Shawwal.
The Prophet ﷺ said: "Whoever fasts Ramadan and follows it with six days of Shawwal, it is as if he fasted the entire year." The math: 30 days × 10 (each good deed multiplied) = 300 days + 6 days × 10 = 60 days = 360 days = one full year. This du'a asks for two things: acceptance of Ramadan (the hard part is over, but was it accepted?) and strength for Shawwal (the bonus round that completes the equation).
