In the sub-continent and many parts of the Muslim world, children fall asleep to the tunes of la ilaha ill'Allah* sung often by their mothers.
Every country has its own traditions of lullabies. One thing they all have in common is a soothing effect on recipients of even an older kind. Playing on Al-Baal Café is the song Cancion para dormir by Beatriz Pichi Malen from Argentina.
It can be found among many wonderful world lullabies on the Putumayo Record, Dreamland.
*Arabic for There is no god but Allah. The Islamic testimony of faith.
