شبِ برات اور آتشبازی کی قبیح رسم

شب برات اور آتش بازی کی قبیح رسم
انسان کی ہمیشہ سے خواہش رہی ہے کہ کام تھوڑ ا کر نا پڑے اور اس کی مزدوری اور اُجرت زیادہ مل جائے۔ اللہ تعالیٰ نے بھی کچھ اوقات ایسے مقرر کیے ہیں کہ اس میں دین اسلام پر کار بند شخص تھوڑی سی عبادت کر کے ڈھیروں ثواب کما سکتے ہیں۔ ان اوقات میں لیلۃ القدر یعنی شب برات بھی ہے جو پندرہ شعبان المعظم کی رات ہے اور کروڑوں مسلمان اس رات میں شبِ بیدار ی کر کے اپنے پروردگار کے سامنے سر بسجدہ ہوتے ہیں اور اپنے گناہوں کی معافی کے طلبگار ہوتے ہیں۔ چنانچہ قرآن مجید میں ہے کہ:۔
’’حم قسم ہے کتاب مبین کی بیشک ہم نے اتارا ہے اسے ایک برکت والی رات میں بے شک ہم ڈر سنانے والے ہیں، اس رات ہرحکمت والا کا م بانٹ دیا جا تا ہے۔‘‘
تشریح! یہاں کتاب مبین سے مراد کلام اللہ یعنی قرآنِ مجید فرقانِ حمید ہے اگر چہ بعض مقامات پر اس سے مرادلوح محفوظ بھی ہے۔ نزولِ قرآن کی رات کی عظمت و فضیلت کو ظاہر کرنے لیے اللہ تعالیٰ نے قرآنِ مجید کی قسم ارشاد فرمائی۔ لیلۃ القدر برکتوں والی رات اس رات کے تعین میں مختلف اقوال ہیں لیکن عام طور پرد وقول زیادہ مشہور ہیں ایک تو یہ کہ اس سے مراد لیلۃ القدر ہے جو ماہ ِرمضان شریف میں آتی ہے۔ دوسرا قول یہ ہے کہ اس سے مراد شب ِبرات ہے جو شعبان المعظم کی پندرھویں رات ہے جیسا کہ تفسیر مظہری میں ہے۔ حضرت عکرمہصنے کہا کہ یہ پندرھویں شعبان کی رات ہے جس میں سال بھر کے امور لکھ دیئے جاتے ہیں جنہیں مرنا ہوتا ہے انہیں زندوں کی فہرست سے نکال دیا جاتا ہے پھر ان میں نہ زیادتی کی جاتی ہے نہ کمی۔

عرب عہد جاہلیت میں ’’طلاق‘‘ کا تصور: تحقیقی جائزہ

Conjugal life is an important aspect of human society, on which a prosperous life depends. Almost every Culture, civilization and religion Legislate for family life. There is a part of these laws to end the marital relationship which is denoted by "DIVORCE". Divorce is mentioned in detail in Islamic Sharia, in order to understand them truly one has to genuinely consider and understand the concept of divorce in Pre-Islamic period of ignorance. There were several specific terms for divorce that were used in the Arab culture for example Talᾱq, Īela and Khula etc. But generally decent people use the word "طلاق"(Talᾱq) to end the marital relationship. There were some common causes and reasons for divorce in Arabs before Islam for example lack of mental harmony, infertility, bigotry, family feud and apostasy etc. The divorced women become more and more vulnerable socially and economically in ancient Arab and consequently their children less attention, love and affection of their mothers turning them into rebellious, nonconformist and ruthless individuals crossing all limits of oppression and we often see examples of such incidents in Arabs before dawn of Islam. These cruel customs and practices were uprooted through teachings of Islam which is based on justice, equality and basic human rights.

Antioxidant Properties of Medicinal Plants from Coastal Pakistan

Plants have been a major source of chemicals that are useful in treating various human diseases. Synthetic medicines have gained considerable importance but the necessity of drugs extracted from plants is still high because of the greater beneficial effects and lesser side effects of natural products. Natural substitutes of synthetic products are therefore being investigated from plants that are inexpensive and safe to use. The aims of this study were to conduct detailed ethno-medicinal surveys of the rural communities distributed along coastal and sub-coastal regions of Pakistan; to evaluate antioxidant activity and polyphenolic composition of known medicinal plants; and to identify plant species rich in natural antioxidants. I identified about 100 plant species with medicinal properties and most of them were perennials. Decoctions of above-ground plant parts were commonly used to cure 17 different types of ailments by local inhabitants. Halophytes had higher antioxidant potential and phenolic content compared to non-halophytes. Highest antioxidant capacity was recorded in methanol (80%) extracts of Thespesia populneoides, Salvadora persica, Ipomoea pes-caprae, Suaeda fruticosa and Pluchea lanceolata, which was more than that of synthetic antioxidants. These halophytes accumulated significant amounts of total phenolics (TPC), flavonoids (TFC) and proanthocynidins (PC) with high antioxidant activity in their above ground vegetative parts (leaf and stem) compared to roots and seeds. A strong positive correlation was also observed between polyphenols (TPC, TFC and PC) and antioxidant activity using different testing systems. Major phenolics were salicylic, gallic, and chlorogenic acids while dominant flavonoids were kaempferol, rutin and quercetin dihydrate. My data indicate that halophytes represent a rich source of natural antioxidants besides their medicinal uses and could also be considered as potential alternative to synthetic antioxidants for food, pharmaceutical, cosmetics and other industrial products. These plants could provide sufficient biomass at commercial scale using brackish water and saline lands while sparing fresh water and prime agricultural lands for conventional agriculture.
