This is how Imam al-Haddad (may Allah benefit us by him) describes standing at Arafat:
و في عرفاتٍ كلُّ ذنبٍ مُكَفَّرٌ و مُغْتَفَرٌ مِنَّا بِرَحْمَةِ غَافِرِ
وقفنا بها و الحمدلله و الثنا و شكراً له إن المزيد لشاكِرِ
عشيَّةَ وافى الوفدُ من كل وجهةٍ و فجٍّ و هم ما بين داعٍ و ذاكِرِ
و راجٍ و باكٍ مخافةَ ربِهِ بفائضِ دمعٍ كالسحائبِ المواطِرِ
و في الوفدِ كَمْ عبدٍ منيبٍ لِرَبِّهِ و كم مخبتٍ كم خاشع متصاغِرِ
و ذي دعوةٍ مسموعةٍ مستجابةٍ من الأولياءِ أهلِ الصفا و البصائرِ
و لِلَّهِ كَمْ من نظرةٍ كم عواطفٍ و كَمْ نفحاتٍ للإلهِ غَوامِرِ
و إنا لنرجو عفوَهُ أن يَعُمَّنا و يَشْمُلَ مِنَّا كُلَّ بَرٍّ و فاجِرِ
At Arafat all of our sins are wiped away and forgiven by the mercy of the All-Forgiving
We stood there – all praise to Allah and thanks to Him, and more is given to the grateful
On the evening in which the party assembled from every direction and valley, calling upon Allah and remembering Him
Hoping and weeping out of fear of their Lord, tears pouring down like rain
The party was full of those constantly turning to their Lord, humbled and broken
Those whose prayers are heard and answered among God’s chosen servants, people of purity and insight
Countless gazes, breezes and mercies did Allah pour down
And we hope that we will all receive His pardon, both the good and bad among us
