This is an amazing lecture series [in the Urdu language] on the life of the Prophet Muhammad (may peace and blessings be upon him) consisting of 30 episodes, narrated by Shaikh Muhammad Khair Makki al-Hijazi. Despite any disagreements with Shaikh, this unmatched series will definitely increase your knowledge about the life of the Prophet Muhammad (may peace and blessings be upon him). Listen to these lectures while walking, traveling, or in any time slot available to you. As they say, little by little one walks far. Also, Shaikh doesn't claim to have specialization in any STEM field.
