Prison

Every single one of he 4 Imaams has endured chains and has entered the dungeons of tyrant rulers … they stood up for justice, and opposed oppression. They endured iron & fire and they did not sell their religion for a worldly gain…

The Prophet says:
من قال لا إله إلا الله دخل الجنة
“Whoever says: “La ilaha il Allah”, enters Paradise.”

The tyrant ruler says:
من قال لا إله إلا الله دخل السجن
“Whoever says: “La ilaha il Allah”, enters Prison.”

That’s of course if it’s said according to its actual meaning, not the cute & fluffy understanding of it…
