Imam al-Nawawi’s Advice for Arafah “This is the best day in the year for supplicating, thus it befits a person to fully devote his efforts in making Dhikr, Du'a and reciting the Quran; and he should supplicate with the different kinds of Duas and read the different kinds of Dhikr. He should supplicate for himself, his parents, relatives, mashaykh, companions, friends, loved ones and any one else who was good to him as well as all the Muslims. And let him be fully cautious from falling short in any of these as this day cannot be made up.” [كتاب الأذكار للنووي طبعة دار المنهاج ص ٣٣٣]
