Dua the prophet (Saw) recommended and said that
لَا إِلَهَ إِلَّا اللهُ ، وَحْدَهُ لَا شَرِيكَ لَهُ ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ ، وهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ
Transliteration
laa ilaaha ill-allaahu, waḥdahu laa shareeka lah, lahul-mulku wa lahul-ḥamdu, wa huwa ‛alaa kulli shay’in qadeer
Translation
The best of supplications is the supplication on the day of AAarafah and the best which I and the Prophets before me have said (is):
“None has the right to be worshipped except Allah, alone, without partner. To Him belongs sovereignty and all praise and He is over all things omnipotent.”
“None has the right to be worshipped except Allah, alone, without partner. To Him belongs sovereignty and all praise and He is over all things omnipotent.”
The benefits of Hajj and Arafah reach the entire Ummah, they reach the entire nation. So pray for yourself, pray for your Ummah, pray for the people around the world, your Ummah around the world, and let the benefit flow insahllah taala because this is the most blessed day of the year.
