                ## 💡الهدف هو ترجمة 500 مطالبة
                وكالعادة: البيانات عالية الجودة مطلوبة! لقداختار المجتمع أفضل 500 مطالبة التي ستشكل المعيار. باللغة الإنجليزية، بالطبع.
                **لذلك نحتاج إلى مساعدتك**: إذا قمنا جميعًا بترجمة الـ 500 مطالبة، يمكننا إضافة العربية إلى قائمة المتصدرين.
