The Best Prayer the Prophets Have Said

The Prophet صلى الله عليه و آله وسلم‎ said: “The best thing that I and the Prophets have said on the evening of ‘Arafah is :

 لَا إِلهَ إِلاّ اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ المُلْكُ وَلَهُ الْحَمدُ، وَهُوَ عَلَى كُلِّ شَيءٍ قَدِير

None has the right to be worshipped but Allah* alone, Who has no partner. His is the dominion and His is the praise, and He is Able to do all things.” At-Tirmithi. Silsilatul-‘Ahadith As-Sahihah

the word Allah –as the scholars say – is a name for the One Who Truly Exists and Who encompasses all the Attributes of  Divinity  (Al-Uloohiyyah), Who is described with all the Attributes of Lordship (Ruboobiyyah), and that it is not permissible to call anyone else with it (Allah), as mentioned by Al- Qurtubi  and others.
