Virtue: People often forget the importance of the simple yet powerful dua (supplication) – Istighfar i.e., saying “Astaghfirullah” (I seek forgiveness of Allah). It is the Sunnah of our beloved Prophet (ﷺ) to seek istighfaar 100 times daily.
One of the 99 Names of Allah is Al-Ghaffaar (الْغَفَّارُ) – The Great Forgiver The Forgiver, the One who forgives the sins of His slaves time and time again.
And verily, I am indeed Forgiving to him who repents, believes (in My Oneness, and associates none in worship with Me) and does righteous good deeds, and then remains constant in doing them, (till his death). [Ta-Ha 20:82]
