خواجہ حسن نظامی

خواجہ حسن نظامی
افسوس ہے کہ گذشتہ مہینہ ہندوستان کے نامور بزرگ خواجہ حسن نظامی نے ۷۷ سال کی عمر میں انتقال کیا، ان کی جیسی جامع الحیثیات شخصیتیں مدتوں میں پیدا ہوتیں ہیں، وہ ایک خاندانی اور صاحبِ نسبت صوفی، صاحبِ طرز ادیب، ذہین و ماہر نفسیات داعی، کامیاب تاجر، غرض تنہا ایک دنیا اور دلّی کی تہذیب و شرافت کی یادگار تھے، انہوں نے اپنی محنت اور خداداد ذہانت و قابلیت اور سوجھ بوجھ سے نہایت معمولی حالت سے جس قدر ترقی اور شہرت و ناموری حاصل کی، اس کی مثالیں کم ملتی ہیں ان کا طرز انشاء نہایت سادہ مگر دلنشین اور سہل ممننع کی حیثیت رکھتا ہے۔ انہوں نے بہت چھوٹی چھوٹی اور حقیر چیزوں پر جیسے مفید، دلچسپ، سبق آموز اور نتیجہ خیز مضامین لکھے وہ ان ہی کا حصہ ہے، ان کے مضامین کے کئی مجموعے شائع ہوچکے ہیں، ان کی تصانیف کی تعداد سیکٹروں سے متجاوز ہے ، موضوع کا اتناتنوع اور نشیب و فراز مشکل ہی سے اردو کے کسی مصنف کے مضامین اور کتابوں میں مل سکتا ہے، ان کی تصانیف میں غدردہلی کے افسانوں کا سلسلہ شاہکار کی حیثیت رکھتا ہے، انہوں نے درجنوں اخبارات اور رسالے نکالے، ایک زمانہ میں ان کے زیرپرستی نکلنے والے رسالوں کی سارے ہندوستان میں دھوم تھی، ان کے بہت سے شاگرد اور تربیت یافتہ اڈیٹر اور صاحبِ قلم بن گئے،اس لیے اردو زبان کی خدمت کے اعتبار سے وہ اس دور کے اساطینِ اردو میں تھے۔
ان کے ہر کام میں جدت و ذہانت نمایاں تھی، اور ان کی کامیابی کا سب سے بڑا سبب ان کا یہی وصف تھا، ان کے مریدوں اور عقیدت مندوں کا دائرہ نہایت وسیع تھا، جس میں ہندو، مسلمان، سکھ اور امراء و والیانِ ریاست سب داخل تھے، ایک زمانہ میں انہوں نے...

مشترکہ و جداگانہ خاندانی نظام کے معاشرے پر اثرات

Islam is the full code of life that not only provides guidance to its followers but also is a source of growth for each and every one who has soul. Islam emphasizes on formation of an exemplary society. Basic unit of each society is dependent upon the family system. If family system is inspired with good and healthy values, then the resulting society will certainly be brightened with brilliance of the righteous values. Family and affiliation with family is a natural need for humanity. Since Islam is the nature, therefore it provides us full guidance about the family system and its importance in our whole life. Islam emphasizes on family strengthening and stability. The importance of family relationships and relations with the relatives has also been mentioned in the holy Qur’an. Family is referred as “Usrah” in Arabic, which means being bound or connected. Strongest castle is also known as “Usrah” in Arabic, where members within a family remain united and connected together with strong bonding among them. Keeping in view the needs of a family, Islam has described the fundamental principles related to family system in a very narrative way. Moreover, mutual responsibilities towards each other and other rights have also been mentioned explicitly. Even Islam has emphasized on showing generous compassion, sympathy and providing legal rights to one another. While some of the issues have been left mainstream which people within a society consider good and don’t even contradict the principles of Islam. One such issue is the family system. What should be the nature of family? Is it all in living within one family or in a separate family system? There are two types of family systems in Sharia; Joint and separate family systems. The conditions and circumstances which better suit in an environment with good effects on family as well as society should better be adapted. But it should be kept in mind that the western concept of separate family (wife, children and one’s own-self) being presented today is not an Islamic concept. For explaining these aspects, the present article will focus on “what is the basic concept and Impacts of joint and separate family systems in Islam? And what are the impacts of these family systems on the society (economic, social and psychological)

Integrated Management for Ectoparasitic Mites Varroa Destructor Anderson and Trueman and Tropilaelaps Clareae Delfinado and Baker of Honey Bee Apis Mellifera L. in Relation to Honey Yield

The efficacy of different organic acids, plant oils and extract was evaluated a series of experiments for the control of ectoparasitic mites Varroa destructor Anderson & Trueman (Acrina: Varroidae) and Tropilaelaps clareae Delfinado and Baker (Acrina: Laelapidae), a big threat to honeybee, Apis mellifera ligustica (Hymenoptera: Apidae) populations world-wide. All the experiments were maintained using modified bottom board trays (mechanical control) and maintaining test colonies with regular re- queening with hygienic queens (genetic control). Effectiveness of 4gm thymol and 20 ml formic acid (65%) against T. clareae mite on honeybee colonies was calculated and it was found that formic acid killed significantly higher number of T. clareae mite as compared to thymol and control group. The total honey production harvested from colonies treated with formic acid was higher (14.33 kg) as compared to other groups. Different concentrations of oxalic acid (OA) were tested for their effectiveness against V. destructor mite populations. Average efficacy of OA recorded with 3.2, 4.2 and 2.1 % was 95, 81 and 46 % respectively. The honey produced was also found maximum (23 kg) in 3.2% OA treatment. Different amounts of thymol with 3.2% oxalic acid (OA) on both mite populations in honeybee colonies were also determined. It was found out that average efficacy of 2, 4 and 6 gm thymol with 3.2 % OA for controlling T. clareae was 26, 40, 35 % and for V. destructor it was 93, 99 and 94 %, respectively. The results clearly showed that the 3.2 % OA with 4gm thymol was the best treatment for controlling these mites. The honey produced was also found maximum in (21 kg) 3.2% OA+ 4 gm thymol treatment. The fourth study was conducted in laboratory as well as in bee hives to evaluate the acaricidal effects of some plant oils on Varroa mites. In the laboratory experiments with different oils/extracts, clove oil in combination with tobacco extract proved very effective against under study mites. The treatments were significantly effective when applied in 5 % as compared to 10 and 15 % concentrations. In the second experiment using only 5 % concentration for 24 hrs, the most effective combination was clove oil and tobacco extract. The field experiment with all the oils/extracts individually and in all the previously tested combinations confirmed the lab results as clove oil + tobacco extract the best combination with 96.48 % efficacy. The honey produced was also found maximum (20.5 kg) in clove oil + tobacco extract treatment. In view of the findings of previous studies, the fifth and final experiment regarding integrated management was carried out to determine the effects of three different treatments. i.e. 4gm thymol + 3.2% OA and 65% formic acid (T1), 5% clove oil + Tobacco extract and 4gm thymol+3.2% OA (T2) and 5% clove oil + Tobacco extract and 65 % formic acid (T3) to manage ectoparasitic mites i.e. T. clareae and V. destructor populations in honeybee A. mellifera colonies round the year. Average efficacy was calculated and it was found that T1 had the highest efficacy 86 and 97.75 % for both the mites, respectively. The total honey production harvested from colonies treated with different acaricides was also determined and significantly more amount of honey was produced (30 kg) from the hives treated with 4gm thymol + 3.2% OA and 65% formic acid. It was observed that during all experiments treatment cause no effect upon queen and adult honey bee activities.
