«اللهُمَّ رَبَّ جَبْرَائِيلَ، وَمِيكَائِيلَ، وَإِسْرَافِيلَ، فَاطِرَ السَّمَاوَاتِ وَالْأَرْضِ، عَالِمَ الْغَيْبِ وَالشَّهَادَةِ، أَنْتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ، اهْدِنِي لِمَا اخْتُلِفَ فِيهِ مِنَ الْحَقِّ بِإِذْنِكَ، إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُسْتَقِيمٍ»
{وهو من أدعية استفتاح الصلاة، خاصة في صلاة قيام الليل}
{ويقال عند التباس الحق وورود الشبهة على القلب}
Allahumma rabba Jibrā’īl, wa Mīkā’īl, wa Isrāfīl, Fāṭira s-samāwāti wal-arḍi, ‘Ālima l-ghaybi wa sh-shahādati, anta taḥkumu bayna ‘ibādika fīmā kānū fīhi yakhtalifūn, ihdinī limā ikhtulifa fīhi mina l-ḥaqqi bi-idhnika, innaka tahdī man tashā’u ilā ṣirāṭin mustaqīm
“O Allah, Lord of Jibrāʾīl (Gabriel), Mīkāʾīl (Michael), and Isrāfīl, Originator of the heavens and the earth, Knower of the unseen and the witnessed, You judge between Your servants in what they differ. Guide me to the truth in that over which they differ, by Your permission. Indeed, You guide whom You will to a straight path.”
(This supplication is recited at the opening of the prayer, especially during Qiyam al-Layl.)
(It is also said when the truth is unclear or doubts arise in the heart.)
