المقدمة

الحمد لله رب العالمين الصلاة والسلام على سيدنا محمّد الأمين - صلى الله عليه وسلم- المبعوث رحمة للعالمين وعلى آله وأصحابه أجمعين ومن تبعهم بإحسان إلى يوم الدين.

 أما بعد:                    

فلا شكّ أنَّ البشرية، لم تعرف كتابًا حظي بالدرس، والتمحيص، واحتفاء الناس به، كما هو الحال مع (القرآن العظيم). فمنذ تنزل الوحي على قلب نبينا - صلّى الله عليه وسلّم - لم يتوقف تأثير هذا الكتاب على قـُلوب الناس، وعقولهم؛ وذلك لأنّه نزل مفصلاً، قيمًا، متصفـًا بمعجز النظم كما في قوله تعالى: ﴿لَا يَأْتِيهِ الْبَاطِلُ مِنْ بَيْنِ يَدَيهِ وَلَا مِنْ خَلْفِهِ تَنْزِيلٌ مِنْ حَكِيمٍ حَمِيدٍ﴾ (فصلت: 42). جعله الله متلوًا لا يمل على طول التلاوة، وعجيبًا لا تنقضي عجائبه.

وقد أنزل الله - عزّ وجلّ - القرآن الكريم بلسانٍ عربيّ مبين، وجعلهُ محكمًا فقال:﴿كِتَابٌ أُحْكِمَتْ آيَاتُهُ ثُمَّ فُصِّلَتْ مِنْ لَدُنْ حَكِيمٍ خَبِيرٍ﴾ (هود: 1). وجعله معجزًا؛ تحدى به العرب، أنْ يأتوا بمثله، أو بسورة من مثله فقال سبحانه وتعالى: ﴿فَأْتُوا بِسُورَةٍ مِنْ مِثْلِهِ وَادْعُوا شُهَداءَكُمْ مِنْ دُونِ اللَّهِ إِنْ كُنْتُمْ صَادِقِينَ﴾ (البقرة: 23). وحكم عليهم بالعجز أنْ يفعلوا ذلك في الماضي، أو الحاضر، أو المستقبل فقال: ﴿فَإِنْ لَمْ تَفْعَلُوا وَلَنْ تَفْعَلُوا فَاتَّقُوا النَّارَ الَّتِي وَقُودُهَا النَّاسُ وَالْحِجَارَةُ أُعِدَّتْ لِلْكَافِرِينَ﴾  [االبقرة: 24]. ولم يكن هذا التحدي للعرب الذين اشتهروا بالفصاحة وحدهم، بل كان للإنس والجنّ قاطبةً، يقول تعالى: ﴿قُلْ لَئِنِ اجْتَمَعَتِ الْإِنْسُ وَالْجِنُّ عَلَى أَنْ يَأْتُوا بِمِثْلِ هَذَا الْقُرْآنِ لَا يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا﴾ [الإسراء: 88].

أما الفصاحة لهذه الايات الكريمة تنمي إلى أدب القرآن فالآداب لا تكون في الإنسان إلا شرائع، ولكن الإنسان إذا عَرِيَ من الأدب النفسي، فربما شرع لنفسه ما لا يصنع الشيطانُ أخبثَ منه بل ما يَركضُ فيه الشيطانُ ركضاً؛ وقلما انتفعَ مَن لا أدب له بشريعة من الشرائع وإن كانت في الغاية التي لا مذهبَ وراءها...

الفكر السياسي الإسلامي وتطوره من الشورى إلى الديمقراطية

There has been a tussle going on between Islam and democracy for many decades in the Muslim world which has benefited most certainly the anarchic factions like kings, lords and army dictators. Though democracy is close to Islam and thought to be the best of all types of governments as majority is authority in it that may make or mar the government. In a democratic setup, the individual and personal rights and freedom are considered which is why it is preferred more these days. Many as Muslim thinkers are also in favor of it, but still there is a large faction of clerical scholars who deem democracy as the root of all evils since it empowers general public as an authoritative and decisive force. However with the passage of time, the Islamic counseling system has evolved and come very close to the spirit of democracy. Therefore, may contemporary scholars hold Islamic counseling and democracy almost similar. This article aims to present a preview of democracy and counseling in the light of what the Ulema (Scholars) say about it.

Synthesis and Syncretism Between Islam and Hinduism in the Indian Subcontinent: An Analytical Study of the Religious Thought During the Sixteenth Century

This analysis of the religious thought of the Indian subcontinent focuses upon the nature of earliest contacts between Islam and Hinduism and also discusses the early Hindu response and resistance to Islam and Muslims. These early contacts resulted in development of some theological and social issues within Hinduism; like the theological interpretation of destruction of age old deities and temples and defeat of Hindu rulers by the Muslim armies, issue of social interaction with the Muslims was a taboo for the Hindu society, likewise the development of monotheistic tendencies in the religious thought of Hindus. The Muslim theologians, intellectuals and Sufis interpreted, categorized and comprehended the religious beliefs and practices of Hindus in different ways. These interactions developed in much divergent ways over the centuries and there emerged a variety of ideological, theological, doctrinal and mystical tendencies as a result of these interactions. For an analysis of the nature of these tendencies the issue of religious freedom and conversion activity is discussed in detail. The religious thought of sixteenth century Indian Subcontinent presents an array of different sects and movements that developed as a result of Hindu-Muslim interactions. Some of the sects and movements that emerged as a result of convergence of Hindu- Muslim thought during the sixteenth century were attempts at synthesis between both Islamic and Hindu beliefs and practices while majority of these sects and movements were syncretistic. Synthesis and syncretism are used as two analytical categories; synthesis is an attempt at putting together of common elements while syncretism is an attempt to combine ideas that are disparate and may even be contrary to one another such as the notions of polytheism and monotheism.
