وَجَّهْتُ وَجْهِيَ لِلَّذِيْ فَطَرَ السَّمَاوَاتِ وَ الْاَرْضَ

wajaht wajhi liladhi fatar alsamawat w alaard

I have turned myself wholly towards the One who originated the heavens and the earth

In al-Ehtejaaj: From Muhammad ibn Abdillah ibn al-Humayri – in a hadees on the answers to his questions from the one who is divinely protected: ...So he (a.s.) answered him:
The tawajjuh is entirely non-obligatory, and the highly recommended sunnah which has been agreed upon is (for one to recite):

حَنِيْفًا مُسْلِمًا وَ مَا اَنَا مِنَ الْمُشْرِكِيْنَ.

hanifana muslimana w ma aana min almushrikina.

and I am not from the polytheists.

اِنَّ صَلَاتِيْ وَ نُسُكِيْ وَ مَحْيَايَ وَ مَمَاتِيْ

inna salati w nusuki w mahyay w mamati

Verily my prayer and my sacrifice and my life and my death

لِلهِ رَبِّ الْعالَمِيْنَ لَا شَرِيْكَ لَهٗ وَ بِذٰلِكَ

lilh rabi alealamin la sharik lahٗ w bidhlik

are for Allah, the Lord of the Universe – He has no partner; and this is what

اُمِرْتُ وَ اَنَا مِنَ الْمُسْلِمِيْنَ. اَللّٰهُمَّ اجْعَلْنِيْ

aumirt w aana min almuslimina. aalllhuma ajealni

I was commanded and I am from those who submit. O Allah! Place me

مِنَ الْمُسْلِمِيْنَ. اَعُوْذُ بِاللهِ السَّمِيْعِ

min almuslimina. aaeudh biallh alsmie

among those who submit. I seek refuge with Allah

الْعَلِيْمِ مِنَ الشَّيْطَانِ الرَّجِيْمِ.

alealim min alshaytan alrajimi.

from the accursed Shaytan.

بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ.

bism allh alrahmn alrahimi.

In the name of Allah, the All-beneficent the All-merciful.

and then recite (Surah) al-Hamd.
