Wayfarer refers to the needy traveller, i.e those that travel on foot.

"Alms-tax is only for the poor and the needy, for those employed to administer it, for those whose hearts are attracted ˹to the faith˺, for ˹freeing˺ slaves, for those in debt, for Allah's cause, and for ˹needy˺ travellers. ˹This is˺ an obligation from Allah. And Allah is All-Knowing, All-Wise." Quran 9:60
