[Vedun*]

To gather knowledge is obligatory for every Muslim man and every Muslim woman.

On the Day of Judgement if some one says that he did not implement Islam in his life because he did not know about it then this is one excuse that shall not be accepted of him. He will be asked why did he not make effort to know about it. Allah(SWT) will tell him that he was given extremely strong desire to inquire about the meaning and purpose of life. This desire is stronger than all other desires. Hence anybody trying to ignore it must make tremendous efforts to do so. Such a person will have no excuse on that day - he will be acutely aware of his efforts that he made to suppress this call of Lord.

Then there is the Tradition about beloved Prophet(PBUH) supplication for protection from harmful knowledge.
So can knowledge also harm? Why not? Take the following quotation from a blog post here at SF.

Paying attention to your spiritual ailments is better than turning your gaze in the direction of attaining things which are out of your sight.

O Mureed! You are eager to discover hidden entities. You desire to know of the Divine Mysteries, secrets and subtleties. You consider these entities to be the Maqsood (Goal) or the introductory stage of the Maqsood. Remember that to incline the heart in this direction and to pursue these hidden entities are not for your welfare. In fact, this attitude is harmful for you. It is better for you to view your spiritual defects such as riya, hasad, takabbur, etc., and to concern yourself with their elimination.

If in the course of your spiritual journey some mystery is revealed to you, do not attach significance to it. Keep in mind that your purpose is the purification of your nafs from evil attributes.

Expel every human quality which stands in opposition to your worship (and obedience of Allah) so that you become one who answers the Call of Allah and gain His Proximity.

IKMALUSH SHIYAM
published by themajlis.net There is a clear hint that our activity of knowledge acquisition should be exercised with utter responsibility.

One of the questions of hereafter is how much did you act upon the knowledge that you gathered.
Clearly greed is bad even if it is exercised in the acquisition of knowledge.

Knowledge comes with several responsibilities.
To act upon it.
To communicate it.
To add to it.

May Allah(SWT) grant us the taufeeq to be moderate in this aspect.

Wassalam
