The strength of Imam Abu Hamid Muhammad al-Ghazali, which immortalized him as a proof for Islam, was that he was able to stand on those flowing currents of philosophical dialogues, dialectical debates, and jurisprudential disputes, and to make the Islamic force opposing that whirlwind concentrated in him and represented in his teachings and shouts derived from the Qur'an and Sunnah. He was more like a national leader. He grew up among a people who were torn, weak, and weak in spirit. He united their ranks, renewed their spirit, and revived their faith. Al-Ghazali sent a new, old cry, old because it was the cry of Islam in the Arabian Peninsula for centuries. It is new because it appeared in a society that, drowned in seas of controversy and sophistry, was about to forget its first nectar.
