Because of the great development that took place in information transfer and communication technologies, the issue of information transfer security has become a very sensitive and resonant issue, great importance must be given to protecting this confidential information. Steganography is one of the important and effective ways to protect the security of this information while it is being transmitted through the Internet, steganography is a technology to hide information inside an unnoticeable envelope object that can be an image, video, text or sound. The Arabic language has some special features that make it excellent covers to hide information from Through the diversity of the Arabic letters from dotted letters in several forms or vowels or special letters, the Holy Qur’an is considered a cover rich in movements and Arabic grammar, which makes it a wide cover for the purpose of concealing information. The Holy Qur’an is a sacred book where it is not permissible to modify, add or move any of the letters or any diacritical mark to it. The algorithm hides the two bits by uses six special letters of Arabic language. Moreover, it checks for the presence of specific Arabic linguistic features referred Arabic diacritics. The proposed system achieved a high ability to hide as in Surat Al-Baqarah (4524 bits) and also (2576 bits) in Surat Al-Imran and in Surat Al-An’am (2318 bits).
