Dzulhijjah: The Best Du'a Is The Du'a On The Day of Arafah & Note The Most Important Dzikr Recited On That Day

وَعَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: " *خَيْرُ الدُّعَاءِ دُعَاءُ يَوْمِ عَرَفَةَ* وَخَيْرُ مَا قُلْتُ أَنَا وَالنَّبِيُّونَ مِنْ قَبْلِي: *لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْء قدير* ". رَوَاهُ التِّرْمِذِيّ

وروى مالكٌ عَنْ طَلْحَةَ بْنِ عُبَيْدِ اللَّهِ إِلَى قَوْلِهِ: «لَا شريك لَهُ»

  صَحِيح, صَحِيح   (الألباني)حكم   : 

‘Amr b. Shu'aib, on his father’s authority, quoted his grandfather as saying that the Prophet said, 

*“The best supplication is that on the day of ‘Arafah*, and the best thing which I and the prophets before me have said is,

*لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْء قدير*

‘There is no god but Allah alone who has no partner; to Him belongs the dominion, to Him praise is due, and He is omnipotent’.’’ 

Tirmidhi transmitted it, and Malik transmitted on the authority of Talha b. ‘Ubaidallah up to “who has no partner.”
