I believe and am Firm about it, That Everything Happens With The Will of Allah Allmighty And Without His Will A Single Leaf From The Tree Does not move, Until and Unless Allah Wills So.
Everything is from Allah then why do we believe that a black cloth will protect us from evil eye or anything else. Yes there is a lot of things Allah has Created but Allah is the final and only authority over everything.
My sincere apologies if I have in any manner have hurt any ones feelings regarding this matter.
