The Day of `Arafah
The Day of `Arafah - Prophet Muhammad said: "The best supplication (du`aa’) is that of the day of `Arafah, and the best thing, that I and other prophets before me said, is: La ilaha illa allahu wahdahu la sharika lah, lahu al-mulku wa lahu al-hamdu wa huwa `ala kulli shai'in qadeer (there is no god but Allah alone. He has no partners. To Him belong the sovereignty and all praise. He has power over all things).” (At-Tirmidhi)
