I recited this verse to Ikrimah (may Allah have mercy on him): ﴿Afa lam yay’asi alladhina kafaru﴾, so he said: This is ﴿Falyatabayyan alladhina amanu﴾. Then I mentioned this to Shahr bin Hawshab (may Allah have mercy on him), and he said: He spoke the truth, Ibn Abbas (may Allah be pleased with them both) had referred me to this as well.
