Wounds, Wound Healing And Complications Wounds, Wound Healing And Complications Presentation Transcript

  • In the Name of Allah, the Most Beneficent, the Most Merciful And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty). (2) And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allah, then He will suffice him. Verily, Allah will accomplish his purpose. Indeed Allah has set a measure for all things. (3) Surat Aţ-ŢalāqWounds, Wound Healing And Complications ELHAWARY
