(35:19) Not equal are the blind and the seeing, (35:20) Nor are the darknesses and the light, (35:21) Nor are the shade and the heat, (35:22) And not equal are the living and the dead. Indeed, Allah causes to hear whom He wills, but you cannot make hear those in the graves. (35:23) You, [O Muhammad], are not but a warner. (35:24) Indeed, We have sent you with the truth as a bringer of good tidings and a warner. And there was no nation but that there had passed within it a warner. (35:25) And if they deny you - then already have those before them denied. Their messengers came to them with clear proofs and written ordinances and with the enlightening Scripture.
