Dr. Israr Ahmad comprehensively explains the profound concept of *tazkiya* (self-purification) as outlined in the Quran. He breaks down the process into four essential stages: purification of thought (*tathir-e-fikr*), purification of the *nafs* (lower self), purification of the heart (*tasfiya-e-qalb*), and illumination of the soul (*tajalliy-e-ruh*). He emphasizes that true progress requires removing obstacles to spiritual growth, addressing both internal and external influences. The lecture highlights the Quran as the primary tool for *tazkiya*, detailing how it affects the intellect, the heart, and the soul. Dr. Ahmad draws parallels between the Quran's wisdom and the purification process, explaining how its verses resonate with the human spirit. He concludes by referencing the teachings of Iqbal and Hadith, further illustrating the importance of confronting and reforming the inner self, and how the Quran can transform an individual’s life.
