In Sermon (133), Imam Ali (a.s.) responded harshly to Mughirah ibn Akhnas's attempt to speak in support of Uthman. This sermon was delivered during a time when political divisions in the Islamic community had intensified. The discussions arose from the growing discord between Imam Ali and Uthman ibn Affan. Mughirah intervened on behalf of Uthman, prompting a firm rejection from the Imam.

In this sermon, Imam Ali referred to Mughirah as the son of a cursed one and the fruit of a tree that has neither root nor branch, illustrating Mughirah's lack of worth and substance. These words signify that the Imam viewed Mughirah's support as not only ineffective but also as a reflection of his undesirable character. By stating that Allah does not grant victory to those who have such a supporter, the Imam emphasizes that true success and honor are tied to divine favor and righteous deeds.

This sermon teaches us the importance of carefully choosing our supporters and allies. If our supporters lack foundation, the likelihood of our success diminishes. It also serves as a reminder that Allah's assistance is always with those who tread the path of sincerity and truthfulness, reinforcing the notion that genuine strength comes from a righteous cause.
