'And I do not say to you that I possess the treasures of Allah'—that is, the treasures of Allah's knowledge—'nor do I say to those whom your eyes hold in disdain.'
Muhammad said: "Tazdari" means to deem them insignificant and despise them.
'Allah will never give them any good' in the hereafter; that is to say: He will certainly give them good for that, if their hearts are sincere.
