Ustadh Nouman Ali Khan gives an impactful lecture relating to Surah Al Waqiah and its last part deals with those who are skeptical in light of Deen.
He goes on to cite various examples that illustrate our complete uninhibited dependence on Allah SWT for the smallest of our actions and needs. Yet we choose to adorn the mask of arrogance and vain without realizing that Allah is the provider of sustenance and all this could be taken away with the blink of an eye.
Hence, it is of paramount importance that we fully comprehend the gravity of the Ayats discussed in this lecture and adopt humility and gratitude of the highest degree.
