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-Ţalāq

Wounds, Wound Healing And Complications

  • 1. 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-Ţalāq Wounds, Wound Healing And Complications ELHAWARY
