Du'a on Day of Arafah

بسم الله الرحمن الرحيم 

اللّهُـمَّ إِنِّـي أسْـأَلُـكَ العَـفْوَ وَالعـافِـيةَ في الدُّنْـيا وَالآخِـرَة ، اللّهُـمَّ إِنِّـي أسْـأَلُـكَ العَـفْوَ وَالعـافِـيةَ في ديني وَدُنْـيايَ وَأهْـلي وَمالـي ، اللّهُـمَّ اسْتُـرْ عـوْراتي وَآمِـنْ رَوْعاتـي ، اللّهُـمَّ احْفَظْـني مِن بَـينِ يَدَيَّ وَمِن خَلْفـي وَعَن يَمـيني وَعَن شِمـالي ، وَمِن فَوْقـي ، وَأَعـوذُ بِعَظَمَـتِكَ أَن أُغْـتالَ مِن تَحْتـي

Allāhumma innī as'aluka 'l-`afwa wal-`āfiyah fid-dunyā wal-ākhirah, Allāhumma innī as'aluka 'l-`afwa wal-`āfiyah fī dīnī wa dunyāya, wa ahlī, wa mālī, Allāhummastur `awrātī, wa āmin raw`ātī, Allāhummaḥfaẓnī min bayni yadayya, wa min khalfī, wa `an yamīnī, wa `an shimālī, wa min fawqī, wa a`ūdhu bi`aẓamatika an 'ughtāla min taḥtī.O Allah, I seek Your forgiveness and Your protection in this world and the next. O Allah, I seek Your forgiveness and Your protection in my religion, in my worldly affairs, in my family and in my wealth. O Allah, conceal my secrets and preserve me from anguish. O Allah, guard me from what is in front of me and behind me, from my left, and from my right, and from above me. I seek refuge in Your Greatness from being struck down from beneath me.
