I asked ‘A’ishah: By what words the Prophet ﷺ used to begin his prayer when he stood up at night (to offer tahajjud prayer). She said: When he stood up at night, he began his prayer by saying: O Allah, Lord of Jibra’il, Lord of Mik’ail, and Lord of Israfil, Creator of the Heavens and the Earth, the Knower of what is seen and of what is unseen; Thou decides between Thy servants in which they used to differ. Guide me to the truth where there is a difference of opinion by Thy permission. Thou guidest anyone Thou wishes to the right path. (Using translation from Abū Dāʾūd 767)   

عَائِشَةَ ؓ بِأِيِّ شَيْءٍ كَانَ النَّبِيُّ ﷺ يَفْتَتِحُ الصَّلَاةَ إِذَا قَامَ مِنَ اللَّيْلِ؟ قَالَتْ كَانَ إِذَا قَامَ مِنَ اللَّيْلِ يَفْتَتِحُ صَلَاتَهُ اللهُمَّ رَبَّ جِبْرِيلَ وَمِيكَائِيلَ وَإِسْرَافِيلَ فَاطِرَ السَّمَاوَاتِ وَالْأَرْضِ عَالِمَ الْغَيْبِ وَالشَّهَادَةِ أَنْتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ اهْدِنِي لِمَا اخْتَلَفُوا فِيهِ مِنَ الْحَقِّ بِإِذْنِكَ إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُسْتَقِيمٍ
