The Quranic Teachings

     "O Mankind! There has come to you from your Guardian-Lord an exhortation, a prescription
for the minds, a guidance and beneficence for those who believe" [10:57].
 

Never wish that a blessing or a cause of happiness may depart from its possessor and become transferred to you. However there is no harm in wishing that you may also have the similar blessing or a cause of happiness without desiring that others may become deprived of it. Neither have a feeling of grudging admiration nor harbor any spite or resentment at seeing the success of another.

[Reference verses for Hasad (envy): 2:109, 4:54, 48:15, 113:5]

Important

And do not follow (blindly) any information of which you have no (direct) knowledge. (Using your faculties of perception and conception, you must verify it for yourself. (In the Court of your Lord,) you will be held accountable for your hearing, sight, and the faculty of reasoning."[17:36]
