Maximising the greatest days of the year.
The Prophet, peace and blessings be upon him, said, “No good deeds are better than what is done in these first ten days of Dhul-Hijjah.”
Consistency nurtures sincerity because it trains your good deeds to transcend all purposes besides Allah. When you maintain your good deeds through thick and thin, no matter the people around you, no matter where you are, no matter how you feel, no other purpose is left except for Allah. To build sincerity, build consistency in your good deeds and take them with you everywhere you go.
