The Meaning of the Poet's Words: "And they threw it with them, and the one afflicted among the people of the fortress was from them, above the one of disbelief, so it combined from their disbelief and the agreement of those in the fortress, types of tyranny"

The Shaykh :"And they threw it with them, and the one afflicted among the people of the fortress was from them, above the one of disbelief"
This means that the harm that befell the people of the fortress from these who conspired with the disbelievers became more severe than the harm of the disbelievers, because when a disbeliever accuses the people of the Sunnah of something, everyone refutes his statement and everyone turns away from it. But when a person from the people of the religion sets up the mangonel against the people of the Sunnah, that becomes more severe, because the person from the people of the religion is accepted more than the disbeliever. He said:
"So it combined from their disbelief and the agreement of those in the fortress, types of tyranny"
Because the enemy became now from within and from without.
"And the greatest calamity befell Islam from those two, by the decree of the Most Merciful"
"From those two" refers to the one who was outside the fortress and the one who was inside the fortress.
