ASK 14

In this clip Dr Israr Ahmed explains that optional (Nafl) fasting on the 13th, 14th, and 15th of the lunar month is very rewarding, as it's like fasting the whole month. Fasting on Mondays and Thursdays is also encouraged. While fasting on Fridays alone is not preferred, it's allowed on important days. After Ramadan, fasting six days in Shawwal is recommended for extra blessings.
