علم بڑی دولت ہے

علم بڑی دولت ہے
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
قُلْ ھَلْ یَسْتَوِی الَّذِیْنَ یَعْلَمُوْنَ وَالَّذِیْنَ لَا یَعْلَمُوْن۔صَدَقَ اللہ الْعَظِیْم
صاحب صدر معزز اسا تذہ کرام اور میرے ہم مکتب ساتھیو! آج مجھے جس موضوع پر تقریر کرنے کا موقع فراہم کیا گیا ہے وہ ہے:’’علم بڑی دولت ہے‘‘
صدرِذی وقار!
انسان حسن و جمال میں ایک دوسرے کے برابر ہوسکتا ہے، رنگ و روپ میں ایک دوسرے کے برابرہوسکتا ہے۔ قد کاٹھ میں ایک دوسرے کے برابر ہو سکتا ہے، گفتار ورفتار میں ایک دوسرے کی برابری کر سکتا ہے تحریرو تقریر میں یکسانیت کا امکان ہے، مال و دولت میں ہم پلہ ہوسکتا ہے، سونے چاندی کے ڈھیر کے پیما نے برابر ہو سکتے ہیں، قوت وسطوت میں برابری ہوسکتی ہے لیکن علم ایک ایسی دولت ہے جس میں جاہل اور عالم برابر نہیں ہو سکتے جس کے ترازوکا پلڑاعلم کے وزن سے بھاری ہو جاتا ہے پھر دنیا کی کوئی شے اس کا مقابلہ نہیں کر سکتی اس کے پلڑے کو اُوپر اٹھانا تو در کنار اس کی برابری کا تصور تک نہیں کر سکتا۔
معزز سامعین!
یہ صرف میں نہیں کہہ رہا کہ علم بڑی دولت ہے، بلکہ تاریخ اسلام کی نامور ہستیوں نے کہا۔ صالحین نے کہا کہ علم بڑی دولت ہے، متقین نے کہا کہ علم بڑی دولت ہے، اولیاء نے کہا کہ علم بڑی دولت ہے، ابدال نے کہا کہ علم بڑی دولت ہے، قطب نے کہا کہ علم بڑی دولت ہے، غوث نے ہزاروں کے مجمعے میں پیغامِ تو حید پہنچا کر کہا کہ علم بڑی دولت ہے،حضرت بلال ص نے اپنے آپ کوتپتی ر یت پر لٹا کر کہا کہ علم بڑی دولت ہے، خبیبص نے خود کوسولی پر چڑھا کر کہا کہ علم بڑی دولت...

أوهام الإمام البزار فى الأسانيد والرجال من خلال مسنده البحر الزخار

Indeed، the Sunnah of the Prophet (peace be upon him) is the second sources of Islamic Shariah. It is the sacred knowledge after the Holy Qur’an. It consists of sayings، actions and approvals of the Prophet (peace be upon him). The science of Jarh wa al-Ta’deel (narrator criticism and evaluation) is an important science for the protection of Sunnah. This science comprehensively draws differences of Saḥīḥ from Dha’īf. The religious scholars have started working on Jarh wa al-Ta’deel from the time of companions and successors. Among them a great Moḥaddis was Imām Abu Bakr  Ahmad bin ‘Amr Baẓẓār. He has written the book، “Al-Musnad Al-Bahar Al-Ẓakhkhār”. This book consists of a huge compilation of Aḥadīth and its science. Imām Bazzār has discussed about Asānīd، Ahwāl Rijāl، Ilal Aḥadīth، Mutābi’āt and Tafarradāt. He had adopted a unique research methodology، however، he was among lenient Imāms of Jarh wa al-Ta’deel. Sometimes، he misunderstood reporters and reports. This article attempts to analyze his methodology as a lenient Imām while discussing chains of reporters and reporters of Aḥadīth. This study uses a critical and comparative research methodology to investigate reporters and reports and will be beneficial for researchers and scholars in the field of Hadith and its Sciences.

Ecological Relationship Among Ground Water Breeding Mosquitoes and Population Dynamics of Karachi and Thatta District

The present research of larval breeding sites was performed. The larvae of 14-species of mosquito comprising 3-genera viz. Anopheles, Culex and Aedes were collected from different ground water habitats in Karachi and Thatta of Sindh province, Pakistan, during four years period from 2004 to 2007. A total of 94800 mosquito larvae were collected, out of all these larvae 13.82% was belonged to genus Anopheles, 81.03% to genus Culex and only 4.77% belonged to genus Aedes. Over all collection during 2004 to 2007, the Anopheles was found 16.00%, 14.11%, 11.93% and 13.38% respectively. While Culex larvae were found 79.90%, 82.41%, 80.84% and 82.31respectively during 2004 to 2007, whereas Aedes larval population was recorded as 4.09%, 3.48%, 7.23% and 4.31% during four years. Among Anopheles six species were found which are An. annularis, An.culicifacies, An. pulcherrimus, An. nigerrimus, An. stephensi and An. subpictus (12,974 larvae were studied and identified). Similarly six species of Culex genus (77,192 larvae were studied and indentified) as Cx.xx bitaeniorhynchus, Cx. fuscocephalus, Cx. pipiens fatigans, Cx. pseudovishnui, Cx. tritaeniorhynchus and Cx.vagans. In the same way two species of Aedes, aegypti and Aedes albopictus were also found. Culex genus was the most common and showed highest percentage among Culex species, the Cx. tritaeniorhynchus and Cx. pipiens fatigans exhibited the greatest range of habitat. Among Anopheles, An. culicufacies and An. stephensi breeds in almost any available type of water, but An. stephensi was inversely related to temperature as for as Aedes mosquito concerned, Ae. aegypti percentage was always very high as compared to Aedes albopictus. Highest number mostly was found in the month of October, every year. It is to be noted that larvae fauna depends not only the type of habitat but also on the physical and chemical composition. Some species have positive association and some restricted only in clean water. In the present thesis different experiments were conducted for the resistance on mosquito larvae of District Karachi and Thatta, Mosquito larvae were exposed to neem formulation, the Biosal (10 EC) available locally in the market, a synthetic pyrethroid, deltamethrin (10 EC) andxxi Acorus calamus extract were used. The LC 50 values were calculated simultaneously the two enzyme (GOT, GPT) were estimated in mosquito larvae. Residue analysis and rate of biogradation was also noted by HPLC The LC 50 values of Biosal deltamethrin and Acorus calamus extract against mosquito larvae were computed as 1605.05 ppm, 0.6119 ppm and 70.64 ppm respectively. The enzyme activity pattern and inhibition by Biosal, deltamethrin and Acorus calamus extract were estimated after treatment with LC 50 values of the under test insecticides. The inhibition of GOT produced by biosal, deltamethrin and Acorus calamus extract was calculated as 5.78%, 26.66% and 5.83% respectively. Whereas for GPT the inhibition was 3.95%, 19.65% and 13.77% respectively. The residue analysis by HPLC shows that 97.79%, 87.87% and 78.18% residue of biosal were detected in 24, 48, and 72 hours exposed samples as compared to standard biosal sample. While 98.66 %, 98.49% and 70.45% residues of deltamethrin were detected in 24 hours, 48 hours and 72 hours exposed samples. Whereas 94.63%, 71.65% and 66.25 % residue of Acorus calamus extract were found in 24 hours, 48 hours and 72 hoursxxii exposed larvae. The residue analysis by HPLC indicated that the biodegradation is faster in biosal as compared to Deltamethrin and Acorus calamus samples, which indicate that Biosal degrade quicker and this may be concluded that toxicity of pesticide if compared to each other, is in the following sequence Biosal > Acorus calamus > Deltamethrin. Enzyme inhibition values and HPLC residue analysis, possibly proves the hypothesis that the pesticides obtained from neem and other plant and trees are not only less harmful but safer for our environment, but less prone to the development of resistance.
