The Prophet (ﷺ) rode a camel named 'Kaswa'. At Mash'arul Haram in Muzdalifah, he faced the Qibla and prayed. Then he said takbeer -
اَللَّهُ أَكْبَرُ
Transliteration
Allahu 'Akbar
Translation
Allah is the Most Great.
He said La ilaha illallah
لَا إِلَهَ إِلاَّ اللَّهُ
Transliteration
Laa 'ilaaha 'illAllaah
Translation
None has the right to be worshipped but Allah alone.
And declared His Oneness (Tawheed)
اَللَّهُ أَحَدٌ
Transliteration
Allahu Ahad
Translation
Allah is the one.
