اللّهُـمَّ إِنِّـي أَسْأَلُـكَ بِأَنَّ لَكَ الْحَـمْدُ لا إِلـهَ إِلاّ أَنْـتَ وَحْـدَكَ لا شَـريكَ لَـكَ المَنّـانُ يا بَديـعَ السَّمواتِ وَالأَرْضِ يا ذا الجَلالِ وَالإِكْـرام، يا حَـيُّ يا قَـيّومُ إِنِّـي أَسْأَلُـكَ الجَـنَّةَ وَأَعـوذُ بِـكَ مِنَ الـنّار

64.Allahumma innee as-aluka bianna lakal-hamd, la ilaha illa ant wahdaka la shareeka lak, almannan, ya badee'as-samawati wal-ard, ya thal-jalali wal-ikram, ya hayyu ya qayyoom, innee as-alukal-jannah, wa-a'oothu bika minan-nar.

O Allah, I ask You as unto You is all praise, none has the right to be worshipped except You, alone, without partner. You are the Benefactor. O Originator of the heavens and the Earth, O Possessor of majesty and honor, O Ever Living, O Self-Subsisting and Supporter of all, verily I ask You for Paradise and I take refuge with You from the Fire.
