The Day of Judgment and preparing for the Sirat (bridge).

The sermon describes the Day of Judgment as the most terrifying hour, where hearts are filled with fear and dread. It details the crossing of the Sirat (bridge) over Hell, a decisive moment leading to either eternal bliss or severe punishment. Allah emphasizes the brevity of worldly life, which will feel like a mere hour compared to the eternal afterlife. The Imam urges preparation for this inevitable day through piety, righteous deeds, and avoiding sins, reminding that only believers who act justly will be saved.
