Truly, We have made it (as) a trial for the wrongdoers.Qatadah said,"The tree of Zaqqum is mentioned as a test for those who are misguided. They said,`Your companion tells you that in the Fire there is a tree, but fire consumes trees.'Then Allah revealed the words:إِنَّهَا شَجَرَةٌ تَخْرُجُ فِي أَصْلِ الْجَحِيمِ
