Burns are an injury caused by exposure to heat or flame. A burn is a type of injury to skin, or other tissues, caused by heat, electricity, chemicals, friction, or radiation. Burns that affect only the superficial skin layers are known as superficial or first-degree burns. When the injury extends into some of the underlying layers, it is described as a partial-thickness or second-degree burn. In a full-thickness or third-degree burn, the injury extends to all layers of the skin. A fourth-degree burn additionally involves injury to deeper tissues, such as muscle, tendons, or bone.
Translation: O Lord of all mankind, remove the difficulty & grant relief (for) there is no One but You who grants relief (cure).
And blow on burnt region.
[Hisnul Hasin (English by Muhammed Rafiq]
Blowing means that the two lips meet a little & blow in such a manner that a very little saliva emits. This applies in all cases where blowing is mentioned To put off the fire or when seeing a fire one should recite Allahu-Akbar.
