Here is the transliteration and meaning for those of us who can't read/understand Arabic:
Allahu Akbar, Allahu Akbar, La Ilaha Ilallahu Wallahu Akbar, Allahu Akbar, Wa Lillahil Hamd.
Allah is the greatest, Allah is the greatest. There is no deity besides Allah and Allah is the greatest. Allah is the greatest and all praises are for Allah only.
