The above question raised by ABRAHAM, is answered in the next verse (No. 82) by himself saying:

      ``Those who have believed, and will not mix their belief with oppression, they are guided and for them is the security.''

      The Arabic word, `ZOLM' translated to oppression, means idolatry and polytheism here; because in Quran S 31: 13 we read:

      ``Remember when Luqman said to his son by way of advice; O, my son! Don't associate any partners with Allah, because polytheism is a great oppression.''
