Text and translation
I was walking through the park when I noticed a wallet. It was lying on a bench beside an empty coffee cup. I looked around, but nobody seemed to be searching for anything. Then I took it to the information office near the entrance. While I was explaining the situation, the owner arrived. He thanked me and checked that his cards were still inside.
كنت أسير في الحديقة عندما لاحظت محفظة. كانت على مقعد بجانب كوب قهوة فارغ. نظرت حولي، لكن لم يبدُ أن أحدًا يبحث عن شيء. ثم أخذتها إلى مكتب الاستعلامات قرب المدخل. بينما كنت أشرح الموقف، وصل صاحبها. شكرني وتحقق من أن بطاقاته ما زالت بداخلها.
