Ustadh Michael Wolfender turns to Surah Al-Ma’ida to show how keeping clean leads to pure faith. Keeping clean grows your faith. Washing purifies sins, character and connections.
This surah has a message of the value of keeping clean, including instructions for wudu or ablution (washing before prayer). As Brother Michael says, purifying yourself prepares you for Allah to fulfill His Blessing on you so we may be grateful.
Ayat 7 - 8 discuss physically purifying the body expiates sins. This then allows inner purity, helping initiate commitment for believers to be firm for Allah and a testimony to the justice of Islam. Be fair in all of your actions.
So this four-step process consists of: 1. Purify 2. Feel good from cleanliness 3. Make internal commitment 4. Be mindful of how you behave with others
All of these actions contribute towards the second level of fasting which includes being mindful of speech and behavior.
