Yes musical toys may be common but there are ways that one can block their children listening to music on the toys, if they wished. My son has a very helpful and educative toy but would not use it for that purpose. He would switch the toy on and select the music option and sit there listening to tunes one after another until we blocked off the music. Then he started to learn the alphabet and knew many letters before he turned 2.

Wa alaykum Salam.
Sorry for late reply, I've had a very busy year. I'm not too sure about Islamic pushing toys but there are many Laptop type toys that teach Duaas, Kalimah's, Surah's etc. One toy I bought for my children that they enjoy playing and have learnt the Arabic alphabet from is the talking Arabic alphabet wooden toy, http://www.islam4children.com/index.php?action=item&id=761. It is a little annoying as some of the letters are pronounced incorrectly but does help them learn.

Wa Alaykum Salaam,

It's quite simple really. You should already know which switched activate Music. Open up the toy, (use a container to hold the screws because they can get lost within seconds). Once opened, located the switches from the inside.

All toys are different, some have switches, some have circuit boards and some have dials. Whatever the case, disconnect the wires (only one needs to be disconnected, cut) that make the connection to that switch. Alternatively, if you don't want to cut wires, you can very easily jam those buttons using paper, tape, card board, or anything that stops the music from being turned on.
