wallekum salam....
knowledge is the best gift u can give someone, but depends on the way u go about it. if your giving knowledge to someone in a patronizing way then what are the chances of tht person using tht piece of knowledge/advice effectively.....
or another thing i have noticed if someone is trying to seek knowledge or questions something, people will say "ohh tht is a sin" and "u shouldnt question it" e.g. on a thread where a guppy asked about "the new Quran" instead of telling her politely "there is no new Quran". Someone went straight at her and told her she was comitting a sin, but she was only seeking knowledge so wats wrong with tht?
Good point, CE. Completely agreed.
Also, Mirch uncle pretty much nailed it, IMO. :)
