Joseph already came to you¹ earlier with clear proofs, yet you never ceased to doubt what he came to you with. When he died you said, ‘Allah will never send a messenger after him.’ This is how Allah leaves every transgressor and doubter to stray—

And indeed Yûsuf (Joseph) did come to you, in times gone by, with clear signs, but you ceased not to doubt in that which he did bring to you: till when he died you said: "No Messenger will Allâh send after him." Thus Allâh leaves astray him who is a Musrif (a polytheist, an oppressor, a criminal, sinner who commit great sins) and a Murtâb (one who doubts Allâh’s Warning and His Oneness).
