When washing the left arm...

When washing the left arm, he should say: اَللّٰهُمَّ لَا تُعْطِنِيْ كِتَابِيْ بِشِمَالِيْ، وَلَا مِنْ وَرَاءِ ظَهْرِيْ، وَلَا تَجْعَلْهَا مَغْلُوْلَةً إِلَیٰ عُنُقِيْ، وَأَعُوْذُ بِكَ مِنْ مُقَطَّعَاتِ النِّيْرَانِ allāhumma lā tuʿṭinī kitābī bishimālī, wa lā min warāʾi ẓahrī, wa lā tajʿalhā maghlūlatan ilā ʿunuqī, wa aʿūdhu bika min muqaṭṭaʿātin nīrān O Allah! Do not give me my book [of deeds] in my left hand, nor from behind my back, and do not chain it to my neck.

I seek refuge with You from the garments of hellfire. When wiping the head, he should say: اَللّٰهُمَّ غَشِّنِيْ بِرَحْمَتِكَ وَبَرَكَاتِكَ وَعَفْوِكَ allāhumma ghashshinī biraḥmatika wa barakātika wa ʿafwik O Allah! Envelop me in Your mercy, Your blessings, and Your pardon.

When wiping the feet, he should say: اَللّٰهُمَّ ثَبِّتْنِيْ عَلَى الصِّرَاطِ يَوْمَ تَزِلُّ فِيْهِ الْأَقْدَامُ، وَٱجْعَلْ سَعْيِيْ فِيْمَا يُرْضِيْكَ عَنِّيْ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ allāhumma thabbitnī ʿalaṣ ṣirāti yawma tazillu fīhil aqdām, waj ʿal saʿyī fīmā yurḍīka ʿannī, yā dhal jalāli wal ikrām O Allah! Keep me firmly on the path on the day when feet shall stumble, and let my efforts be in those things that make You pleased with me, O Possessor of Majesty and Bounty!
