Allaahumma Rabbas-samaawaatis-sab'i, wa Rabbal-'Arshil-'Adheem, kun lee jaaran min (name of the person), wa 'ahzaabihi min khalaa'iqika, 'an yafruta 'alayya 'ahadun minhum 'aw yatghaa, 'azzajaaruka, wajalla thanaa'uka, wa laa 'ilaaha 'illaa 'Anta.
O Allah, Lord of the Seven heavens, Lord of the Magnificent Throne, be for me a support against (say the person's name) and his helpers from among your creatures, lest any of them abuse me or do me wrong. Mighty is Your patronage and glorious are Your praises. There is none worthy of worship but You.
