I don't want to change anything in my appearance, I just want to get a little bit taller through programing my sub-conscious mind, I've heard that our subconscious mind has a unique power to break the barriers for our desires....I just want to get a little bit taller through subliminals, because I feel very insecured about my height....is this permissible in Islam?
Yes it is haram to use subliminals as you are attempting to change your appearance. Allah has made every human unique so why change what you have. Be blessed with what Allah has provided you. I am also a bit self conscious about my height but I try not to think about it as Allah has blessed me with everything I have. Trying to change your appearance is also a sin as you are trying to change what Allah has created.
Set steady to the fitrah created by Allah for us: (Ar-Ruum 30:30)
“So set thou thy face steadily and truly to the Faith: (establish) Allah.s handiwork according to the pattern on which He has made mankind: no change (let there be) in the work (wrought) by Allah. that is the standard Religion: but most among mankind understand not.”
