I usually do aarti sahib before the ardas but the gutka sahib at our house has rehras sahib and ardas straight afterwards and aarti later, that made me wonder if it should be read before of after ardas. Please forgive me for my stupidity ji, I am just starting to do my nitnem and wanted it to be correctly done ji. 

Bhul chuk maaf ji

Do Aarti after Ardaas.
