Ruling on wearing abayahs in which there are threads of gold
Question

                What is the ruling on the yellow strings on men’s outer garments? Some think that these strings are mixed with gold.
Praise be to Allah.
    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.
