Just do it.
Unless by "it" you mean "put the word 'Islam' or 'Muslim' on a custom pair of Air Jordans." In that case, you're out of luck.
A Nike fan by the name of Nabeel Kaukab discovered the curious quirk while browsing the online NikeiD store, where customers build and buy custom footwear. Kaukab took the retail athletics giant to task in a Facebook post Thursday.
"Dear Nike," wrote the 40-year-old New Yorker, "I have a sincere question for your Nike ID team. Today, I was trying to buy a pair of Air Jordans and was checking out the customization features, one of which includes the ability to put short text (up to 6 letters) on them. As I was experimenting with different words to customize my shoes, I noticed that for Nike, neither 'Islam' nor 'Muslim' 'fit within our guidelines.'"
