Each year Shaikh Shahabuddin Suhrawardi would leave Baghdad to perform the hajj. But when he grew old and infirm, food prepared for him on the journey did not please him: he no longer liked to eat cold food. His disciple Shaikh Jalaluddin Tabrizi then devised a way to carry a hearth and a pot on his head, and to keep the hearth lit without burning himself. Whenever the Shaikh wished to eat, his disciple would then serve him hot food!
