اللّهُـمَّ رَبَّ جِـبْرائيل ، وَميكـائيل ، وَإِسْـرافيل، فاطِـرَ السَّمواتِ وَالأَرْض ، عالـِمَ الغَيْـبِ وَالشَّهـادَةِ أَنْـتَ تَحْـكمُ بَيْـنَ عِبـادِكَ فيـما كانوا فيهِ يَخْتَلِفـون. اهدِنـي لِمـا اخْتُـلِفَ فيـهِ مِنَ الْحَـقِّ بِإِذْنِك ، إِنَّـكَ تَهْـدي مَنْ تَشـاءُ إِلى صِراطٍ مُسْتَقـيم
O Allah, Lord of Jibra-eel, Meeka-eel and Israfeel (great angles), Creator of the heavens and the Earth, Knower of the seen and the unseen. You are the arbitrator between Your servants in that which they have disputed. Guide me to the truth by Your leave, in that which they have differed, for verily You guide whom You will to a straight path.
