In this paper a Genetic Algorithm (GA) is proposed to attack an Arabic encrypted text by Vigenere cipher. The frequency of occurrence of Arabic letters has been calculated by using the text of the holy book of Quran, since it has rich language features compared to many other books. The algorithm is tested to find the key letters for different ciphertext sizes and key lengths. The results shows 100% correct letters retrieved from medium size ciphertext and short key length, while 90% of the ciphertext is retrieved from long ciphertext and medium key length, and 82% of the ciphertext is retrieved from long ciphertext and long key.

Image processing technique in general, involves the application of signal processing on the input image for isolating the individual color plane of an image. It plays an important role in the image analysis and computer version. This paper compares the efficiency of two approaches in the area of finding breast cancer in medical image processing. The fundamental target is to apply an image mining in the area of medical image handling utilizing grouping guideline created by genetic algorithm. The parameter using extracted border, the border pixels are considered as population strings to genetic algorithm and Ant Colony Optimization, to find out the optimum value from the border pixels. We likewise look at cost of ACO and GA also, endeavors to discover which one gives the better solution to identify an affected area in medical image based on computational time.

The question of clarifying the meaning of a given Arabic text is a subtle one, especially as high literature texts can often be read in more than one way. Arabic is rich in figurative language and this can lead to variety in meaning, sometimes in ways that either adhere closely or diverge far from the ‘original’ meaning. In order to understand a fine literary text in Arabic, one must have a comprehensive understanding of the issue of taʾwīl, and the concept that multiplicity of meaning does not necessarily lead to contradiction. This article surveys the opinions of various literary critics and scholars of balāgha on this issue with a brief discussion of the concepts of tafsīr and sharḥ, which sometimes overlap with taʾwīl.

The present study discusses the cultural and intellectual movement, now on the point of prevalence in the contemporary Islamic world, which adopts the Western ‘hermeneutical method’ and applies it to the Qur'an in particular, and Islamic religious texts in general. The author shows this movement's complete disregard for the established principles of tafsīr, the traditional Arab-Islamic rules of Qur'anic interpretation and the related Prophetic aḥādīth as preserved in the authenticated Sunna. The author argues that the ‘hermeneutical method’ starts from the preconceived notion that the Islamic heritage is male-centred and biased against women, both theoretically and practically, and, on this basis, proposes that the time has come for an intellectual break with this premise and the re-interpretation of the Qur'an and faith in the light of Western Christian hermeneutics. This paper proposes that this method fails to take historical events and the civilisational Islamic experience into account.
