Supplication of the day of 'Arafah

خير الدعاء دعاء يوم عرفة ، وخيرُ ما قلت أنا والنبيُّون من قبلي : لا إله إلا الله وحدهُ لا شريك لهُ ، لهُ الملكُ ولهُ الحمدُ وهو على كل شيء قدير

Pronunciation

Khayru-d-du'a'i du'a'u yawmi 'Arafah, wa khayru ma qultu ana wa-n-nabiyyuna min qabli: la ilaha illa-llahu wahdahu la sharika lah, lahul-mulku wa lahul-hamd, wa huwa 'ala kulli shay'in qadir.

Translation

"The best supplication is the supplication of the day of 'Arafah, and the best of what I and the prophets before me have said: there is no god but Allah alone, without partner; His is the dominion and His is the praise, and He is capable of all things."
