Fasting Ramadan and the 6 days of Shawwal is like fasting for a lifetime:

Abu Ayyoob (Ra) reported that the Prophet (Sallallahu Alaihi Wasallam) said:

“Whoever fasts Ramadaan and follows it with six days of Shawwaal, it will be as if he fasted for a lifetime.” (Narrated by Muslim, Abu Dawood, al-Tirmidhi, al-Nisaa’i and Ibn Maajah).

So let us grab these immense rewards otherwise there will only be utter regret in the Hereafter.
