This is what I have found so far:
"In conclusion, we may note that a leather neck band, also called kilada, on the camel to avert the evil eye, especially if a bell hang from it, is suggested in one tradition." First Encyclopaedia of Islam: 1913-1936
"Silver bracelets or anklets, most often trimmed with tiny bells, are the most popular choice for children. The sound of the bells would protect the young wearer from evil spirits . . ." Saudi Arabia, Volumes 13-15
"Another group is one which is superstitious and which believes that someone may cast an evil spell upon their animals and they hang these collars [with bells] or ta'awidh around their necks." al-mawrid
I am looking for any additional information. In particular, I am seeking sources that are more detailed on the matter since the sources that I've found barely cover the topic. I am also curious as to whether bells were hung in homes for protection from the evil eye. It would be nice if these sources mention time period as well. Thank you.
