To cleanse the heart from resentment, prayer and forgiving others are essential; the Quran emphasizes the importance of controlling anger and love.
Cleansing the heart from resentment and malice is a significant principle of Islamic ethics. In the Holy Quran, Allah emphasizes the avoidance of grudge-holding and promotes love and friendship. One of the best methods to cleanse the heart from bitterness is through prayer and seeking forgiveness. In Surah Al-Imran, verse 134, Allah states: "And those who spend [in charity] during ease and hardship and who restrain anger and who pardon the people - and Allah loves the doers of good." This verse highlights the necessity of controlling our anger and being able to forgive others to achieve goodness. Furthermore, in Surah An-Nur, verse 22, Allah advises against harboring resentment in our hearts towards one another. This message should also resonate in our daily lives. For instance, if someone harms us, we must strive to understand their situation and clear our hearts of any grudges. Additionally, reflecting on the Quranic verses and remembering the name of Allah can help bring peace to the heart. When one tries to replace bitterness with love and forgiveness, they indeed contribute to the betterment of their soul and mind, which is one of the essential principles of healthy living in Islam.
And those who spend [in charity] during ease and hardship and who restrain anger and who pardon the people - and Allah loves the doers of good.
If it had not been for the favor of Allah upon you and His mercy, and that Allah is Forgiving and Wise.
Once, a candle in the alley of love shed light. Anyone who approached it with a resentful heart found its light dimmed. One day, the poorest man in the city visited the candle. The candle kindly said to him, "Empty your heart from grudges, and let my light shine in your heart!" The man cleared his heart from bitterness and embraced the candle. Thus, he set forth again towards love and kindness.
