Music, Nasheeds and Nazams

Unsuitable words in naats and nazams

Q: I am in a doubt. Nowadays there is been a trend of Islamic naats, naat e sharif which are dedicated to our respective Prophet Muhammed Sallallahu Alaihi Wassalam in which they use words like" tujhe" " tera" tu, I feel that these words are not suitable for our beloved and respected prophet (Sallallahu Alayhi Wasallam). So my question to you is, it permissable to listen or sing such naats?

Naats, nazams and nasheeds

Q: Is it permissible to listen to anaasheed, nazms etc if it does not have any musical instrument involved and follows the rules of Shar'iah i.e. no singing by women. Also if it is not used for entertainment/pleasure and is not interfering in anyway with our ma'mulaat or daily routine?

Learning how to play musical instruments

Q: I want to know if it is permissible for a Muslim child to learn to play a musical instrument such as the organ (electric piano) through classes at home or at a special centre. There is much talk of how music stimulates creativity brain growth and so on. With this in mind would it be haram to permit him to learn? We don't generally listen to music as a family but sometimes we watch (clean) movies or cartoons that have music in them.
Sometimes our son comes home from school and requests a certain song that he heard on the bus or his classmates singing to be played and we oblige by playing the song a few times on the computer. Is this permissible? Also what about allowing small children to listen to nursery rhymes and Islamic songs which have clean lyrics but also music in them - can they do this?
