اول اردیبهشت روز استاد سخن سعدی شیرازی

بر همه ایرانیان و فارسی دوستان مبارک باد

درخت دوستی بنشان که کام دل به بار آرد نهال دشمنی برکن که رنج بی شمار آرد

Plant a tree of friendship that will bring joy to the heart... digging out the seedling of enmity that will bring countless sufferings.... The first of May is the day of commemoration of Saadi, the great master of speech, poet, and prose writer of Iran. Saadi Shirazi lived in the 13th century and his works have had a profound impact on Persian literature and Iranian culture.
