Ruling on wearing abayahs in which there are threads of gold

People with experience were previously asked about what is on
the edges of abayahs of threads and adornments which those who see them may
imagine to be gold, and they said that there is no gold at all in them.
Based on that, wearing an abayah which has this adornment on its edges is
permissible. Assuming that there is any gold in it, it is little, so it is
also permissible, , but if it is certain that there is a lot of gold in it,
then it is haraam to wear it. 

And Allaah is the Source of strength. May Allaah send
blessings and peace upon our Prophet Muhammad and his family and companions.
