2. Al-Baqara (The Cow)

Surah: 2   Aya: 211

211. Sal banee isra-eela kam ataynahum min ayatin bayyinatin waman yubaddil niAAmata Allahi min baAAdi ma jaat-hu fa-inna Allaha shadeedu alAAiqabi
  

  Translation

211. Ask the Children of Israel how many clear Ayât (proofs, evidences, verses, lessons, signs, revelations, etc.) We gave them. And whoever changes Allâh's Favour after it had come to him, [e.g. renounces the Religion of Allâh (Islâm) and accepts Kufr (disbelief),] then surely, Allâh is Severe in punishment.
