The Prophet (ﷺ) said: On the day of 'Arafah - your dua there is the very best. The greatest words I and all the prophets before me said are -
لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيءٍ قَدِيرٌ
Transliteration
Laa ilaaha ill-Allahu, wahdahu laa shareeka lahu, lahul-mulku wa lahul-hamdu, wa huwa ‛alaa kulli shay’in qadeer
Translation
None has the right to be worshiped except Allah, alone, without partner. To Him belongs sovereignty and all praise and He is over all things omnipotent.
On Arafah day, this prayer is number one. The Prophet called it the best. Connect with Allah. Ask for mercy. Your heart fills with peace. Your tongue stays busy with the greatest dhikr.
The Prophet said la ilaha illallahu wahdahu la sharika lahu is number one. Say it with sincerity. Allah is pleased.
Yes. Say it at home. Muslims everywhere say this best dhikr on 9th Dhul Hijjah. Ask Allah for mercy and blessings.
Same powerful dhikr while fasting. La ilaha illallah wahdahu la sharika lahu brings huge rewards. Your heart gets clean.
No fixed number in hadith. Say it as much as you can. More you repeat this dhikr allah, more barakah you get.
There is no god but Allah. Alone. No partner. All praise belongs to Him. All dominion is His.
In Hadith books like Tirmidhi. This masnoon dua is famous. Easy to read. Easy to memorize for every Muslim.
The Prophet named it the best. It has everything: Allah's praise, Tawheed, and humility. All in one short line.
Yes. Start with this best dhikr - praise Allah first. Then ask for anything you need in life.
No. Say it daily for dhikr. But the reward is special - much higher - when you say it as dua on Arafah day.
It is repentance and praise together. Say it from your heart. Sins get wiped. Allah's forgiveness comes near on this blessed day.
