It is obligatory on us to purify our soul.
At the moment of death, there is a sudden change in currency. All the dollars or dirhams you have in your pocket will become worthless. The only things that matter after death are your correct beliefs, good deeds, and sound heart. Success in the hereafter depends on the conditions in our hearts that we carry with us. On the Day of Judgment, neither wealth nor children will be of any use. Only those who come before Allah with a pure heart will be saved.
This book shows you how to purify your soul based on the Quran and authentic Sunnah.
