فرد قائم ربط ملت سے ہے تنہا کچھ نہیں

فرد قائم ربط ملت سے ہے تنہا کچھ نہیں
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز سامعین اور میرے ہم مکتب ساتھیو! آج مجھے جس موضوع پر لب کشائی کی سعادت حاصل ہورہی ہے وہ ہے:’’فرد قائم ربط ملت سے ہے تنہا کچھ نہیں ‘‘
صدرِذی وقار!
فرد ملت کی بنیادی اکائی ہے ،فرد ہے تو ملت ہے، فرد ہے تو قوم کا وجود ہے، فرد ہے تو اس کائنات کی رنگینیاں ہیں، فرد ہے تو اس کا ئنات کی رعنائیاں ہیں ، فرد ہے تواس گیتی کے گلشن میں بہار ہے، فرد ہے تو اس گلستانِ ہستی میں نکھارہے۔
جنابِ صدر!
یہ مصرع ہمیں اتحاد کا درس دے رہا ہے۔ہمیں اتحاد کی بابت آگاہ کر رہا ہے، فردکا وجود ہی اتحاد کی بدولت قائم ہے، اتحادکا لفظ ہے ہی بڑی جاذبیت کا حامل ، یہ جس فقرے میں آ جائے اس کے معنی میں حسن پیدا ہو جاتا ہے، چند اینٹیں متحد ہو جائیں تو مکان کی تعمیر ہو جاتی ہے، چند قطرے متحد ہو جائیں تو بحر بے کنار کی شکل اختیار کر لیتے ہیں۔
صدرِ ذی وقار!
اتحاد جس صورت میں بھی موجود ہو قابل تحسین تصور کیا جاتا ہے، جوقوم آپس میں مربوط ہوتی ہے وہ ہر لحاظ سے خوش و خرم ہوتی ہے، اس کی فضاؤں میں آلودگی کا زہر نہیں ہوتا، اس کے کھلیانوں میں غیر نافع بوٹیاں نہیں اگتیں، اس کے شجر سایہ دار خزاں آشنا نہیں ہوتے ، اس کے میدان ویران نہیں ہوتے ، اس کے ہسپتال آباد نہیں ہوتے۔
جنابِ صدر!
اسلام میں اتحادِ ملی پر بڑا زور دیا گیا ہے، حدیث پاک میں ہے کہ مسلمان مسلمان کا بھائی ہے، مسلمان مسلمان کوگالی نہیں دیتا، مسلمان مسلمان کو برا بھلا نہیں...

ثنائية الفصل والوصل في البحث البلاغي

Fasl and Wasl are the burning topics of ‘ilm ul-Bayan (Arabic Rhetoric) alongside it is very initial element which brings structure, beautification, embellishment and improvement. Many Arab scholars, in particular, Arab pioneer Rhetoricians had discussed and still have been discussing as well as discoursing Fasl and Wasl related matters. They put their all attention deeply to both of them in the discoursing of Qur’an structure. The utmost susceptible scholar Abu Bakr Abd al-Qahir bin ‘Abd arRahman bin Muhammad al-Jurjanī, the figurative personality, who first time in the history had discussed Fasl and Wasl based structures in his two prolific books; Asrar al-Balaghah (The Secrets of Elucidation) and Dala'il al-I’jaz (Intimations of Inimitability) theoretically and practically. Later on it was developed by Abu alQasim Mahmud bin ‘Umar al-Zamakhshari as he applied both theories to his commentary on Holy Qur’an known as “Al-Kashshaaf (the Revealer)”. The following research attempts all fruitful efforts spent by scholars having different ethics. It brings arguments towards where it is required, bringing out a short comparison between contemporary and classical Fasl and Wasl based perceptions resulting in what the scholar thinks in person.

Screening of Tomato Cultivars Against Root Knot Nematodes and Their Biological Management

Research was done on two important groups of nematodes plant parasitic nematodes and insect parasitic nematodes (entomopathogenic nematodes). Among plant parasitic nematodes root knot nematodes are the most important. It has a wide host range. Tomatoes are the most seriously affected by Meloidogyne incognita. Different varieties were tested against M. incognita for susceptibility, invasion and development of M. incognita. Moneymaker, Titano, California, Peelo, Nagina, Riogranade and Pakit were highly susceptible while Fonto, Tarnab, Lima, VF-400, PETO-86 and Samrutti were susceptible. Calmart VFN proved resistant. There was a positive relationship between the inoculum level of M. incognita and root weights and inverse relationship with shoot weights. Effect of plant age on plant susceptibility to nematode infection was also studied. Plant extract of neem, onion, garlic, tobacco, aloevera, cloves and chili was investigated for larval mortality and egg hatching of M. incognita. Mortality of nematodes increased with exposure time and extract concentration. Effect of plant extracts on root knot nematodes applied after root knot nematodes and bare dip root treatment was also studied on plant growth parameters plant height, fresh shoot weight, dry shoot weight and fresh root weight. Among all the plant extracts tested neem proved effective followed by onion and tobacco while chili proved less effective as compared to the other plant extracts.In the second part of thesis, effect of entomopathogenic nematodes S. asiaticum, S. glaseri, H. indica and H. bacteriophora on the development of M. incognita, effect of different inoculum levels, and time of application, live and dead EPN on RKN in addition to the persistence in soil was also studied. Suppression of M. incognita varied with application rate. The high application rates of EPN reduced M. incognita infestation as compared to low rates. Reduction in root knot nematode invasion and development was recorded. Numbers of EPN were reduced in non-sterilized soil. Both dead as well as live entomopathogenic nematodes and their material were responsible for lower invasion by M. incognita in tomato.
