This sermon is a piece of advice from Imam Ali (peace be upon him) to his son Muhammad ibn al-Hanafiyyah during the Battle of Jamal, which took place in 36 AH. The Imam aimed to instill courage and steadfastness in his son while teaching him the etiquette of battle.

Imam Ali emphasized that even if mountains shift from their places, one should not move from their own position. This conveys a vital message about the importance of staying steadfast in one’s beliefs and principles, regardless of how dire the circumstances may seem. It teaches us that we must remain firm in our faith and convictions.

He instructed his son to clench his teeth, symbolizing the need to gather one’s strength and confidence. This serves as a spiritual lesson that one should believe in their own capabilities and resilience. Furthermore, by advising him to 'loan his skull to Allah,' the Imam highlighted the readiness to sacrifice oneself for the sake of divine cause, reinforcing the notion that true support comes from Allah.

Another significant point in this sermon is the advice to disregard the enemy’s numbers and strength. This is a profound wisdom that we should not be intimidated by challenges and adversities but instead have faith in Allah’s assistance.

From this sermon, we learn the importance of remaining steadfast in the face of life’s challenges, placing our trust in Allah, and consolidating our inner strength. These teachings continue to guide us in today’s world as well.
