Abu Salamah said:
“I asked Aishah [may Allah be pleased with her]: ‘With what did the Prophet used to open his Salat when he stood up in the night?’ She said: ‘When he stood up in the night, he would open his Salat by saying: “O Allah, Lord of Jibra’il, Mika’il, and Israfil; Originator of the heavens and the earth, [and] Knower of the hidden and the seen; You judge between Your slaves concerning that which they used to differ, guide me through that which there has been difference concerning the truth, verily, You are upon a straight path (Allāhumma rabba Jibrīla wa Mīkā'ila wa Isrāfīl, fāṭira-samāwāti wal-arḍi [wa] `ālimal-ghaibi wash-shahādati anta taḥkumu baina `ibādika fīmā kānū fīhi yakhtalifūn, ihdini limakhtulifa fīhi minal-ḥaqqi bi'idhnika innaka tahdī man tashā'u ilā ṣirātin mustaqīm).”
حَدَّثَنَا يَحْيَى بْنُ مُوسَى، وَغَيْرُ، وَاحِدٍ، قَالُوا أَخْبَرَنَا عُمَرُ بْنُ يُونُسَ، حَدَّثَنَا عِكْرِمَةُ بْنُ عَمَّارٍ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، حَدَّثَنَا أَبُو سَلَمَةَ، قَالَ سَأَلْتُ عَائِشَةَ رضى الله عنها بِأَىِّ شَيْءٍ كَانَ النَّبِيُّ صلى الله عليه وسلم يَفْتَتِحُ صَلاَتَهُ إِذَا قَامَ مِنَ اللَّيْلِ قَالَتْ كَانَ إِذَا قَامَ مِنَ اللَّيْلِ افْتَتَحَ صَلاَتَهُ فَقَالَ ‏
"‏ اللَّهُمَّ رَبَّ جِبْرِيلَ وَمِيكَائِيلَ وَإِسْرَافِيلَ فَاطِرَ السَّمَوَاتِ وَالأَرْضِ وَعَالِمَ الْغَيْبِ وَالشَّهَادَةِ أَنْتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ اهْدِنِي لِمَا اخْتُلِفَ فِيهِ مِنَ الْحَقِّ بِإِذْنِكَ إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُسْتَقِيمٍ ‏"‏ ‏.‏ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ ‏.‏
