22. Al-Hajj (The Pilgrimage)

Surah: 22   Aya: 53

53. LiyajAAala ma yulqee alshshaytanu fitnatan lillatheena fee quloobihim maradun waalqasiyati quloobuhum wa-inna alththalimeena lafee shiqaqin baAAeedin
  

  Translation

53. That He (Allâh) may make what is thrown in by Shaitân (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimûn (polytheists and wrong-doers, etc.) are in an opposition far-off (from the truth against Allâh's Messenger and the believers).
