40. Al-Ghafir (The Forgiver (God) )

Surah: 40   Aya: 34

34. Walaqad jaakum yoosufu min qablu bialbayyinati fama ziltum fee shakkin mimma jaakum bihi hatta itha halaka qultum lan yabAAatha Allahu min baAAdihi rasoolan kathalika yudillu Allahu man huwa musrifun murtabun
  

  Translation

34. 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, oppressor, a criminal, sinner who commit great sins) and a Murtâb (one who doubts Allâh's Warning and His Oneness).
