مولوی جنید نعمانی
یہ خبر نہایت حسرت و افسوس کے ساتھ سنی جائے گی کہ مولانا شبلی نعمانی مرحوم کے چھوٹے بھائی مولوی جنید صاحب نعانی سب جج کانپور نے دوسال کی صحت و علالت کی کشمکش کے بعد ۱۲؍ اپریل ۱۹۳۳ء کو دہلی میں وفات پائی، مولانا مرحوم کے صرف یہی ایک بھائی تھے جو ان کی وفات کے بعد زندہ تھے، آخر انہوں نے بھی اس دنیا کو الوداع کہا، یہی وہ بھائی تھے جن کی نسبت مولانا نے اپنے بھائی محمد اسحاق صاحب مرحوم الہ آباد ہائی کورٹ کے پر درد نوحہ میں ۱۹۱۴ء میں یہ فرمایا تھا:
اے خدا شبلی دلِ خستہ بایں موئے سپید
لے کے آیا ترے درگہِ عالی میں امید
مرنے والے کو نجات ابدی کی ہو نوید
خوش و خرم رہے چھوٹا مرا بھائی یہ جنید
افسوس کہ یہ بھائی اپنے بڑے بھائی کے بعد اٹھارہ برس سے زیادہ خوش و خرم نہ رہ سکا، دعا ہے کہ مرحوم کو اب آخرت کی ابدی خوشی و خرمی حاصل ہو۔ (سید سلیمان ندوی، مئی ۱۹۳۳ء)
This article dealt with the description of services of Hażrat ‘Āyeshah (R. A) in the field of principles of derivation of legal rules from the legal texts of the Holy Quran and prophetic traditions, which is the second part of the series, in first part Quran was focused in this regard while in this article other sources of Islamic law as Prophetic tradition etc. Have been discussed and their applications in the juristic approach of Hażrat ‘Āyeshah, likewise, Qiyās is a method that uses analogy/ comparison to derive Islamic legal rulings for new developments due to importance and the need of society. Umm Al-Momineen Hażrat ‘Āyeshah (R. A) used to derive a ruling for new situations that are not addressed by Qur’an and Sunnah. Istiḥsān is the fourth principle of derivation of Aḥkām. Likewise, other sources considered by her including Istiḥsān, Istisḥāb, ‘Urf as principle of derivation of Aḥkām. ‘Urf is an Arabic Islamic term referring to the custom or knowledge of a given society. Furthermore, the method adopted for research is deductive. The study found that Hażrat ‘Āyeshah applied the said sources in her process of derivation of legal rules of Islam, which were followed by Muslim jurists in this regard, So it is recommended that student of Islamic Law should study efforts of the companion of Prophet peace be upon him and their principles in the field.
Radon has long been recognized as one of the indoor air problems. There is a strong relation between radon and lung cancer. It is the second leading cause of the lung cancer after cigarette smoking. The present research work concerning the Measurement of seasonal and spatial variation of indoor radon and development of a passive dosimeter for thoron’s progeny is divided into two parts. The first part deals with the field and laboratory measurements which were performed using the passive radon dosimeters and in the second part laboratory experiments were carried out to develop a new passive thoron progeny dosimeter. Chapter 1 gives a brief introduction to radon, its health effects, measurement techniques and the instruments used for the measurement of indoor radon concentration. Different dose conversion relations and excess lung cancer reports have also been discussed in this chapter. Chapter 2 describes different types of equipments and materials used in the research work. Information about the geology, climatic conditions and building characteristics of the houses surveyed have also been given in this chapter. It also includes procedure of the samples preparation for the measurement of radioactivity and radon exhalation rate in the laboratory using active and passive detectors. In chapter 3 reviews reported studies conducted in Pakistan concerning the measurement of natural radioactivity and indoor. Chapter 4 discusses the results and discussion of the present work concerning radon measurement performed throughout the years in four cycles which has covered all the seasons. Seasonal correction factor, weighted average indoor radon levels excess lung cancer risk and the dose delivered to the inhabitants using the local occupancy factor have also been included in this chapter. Chapter 5 deals with the results and discussions about the radon exhalation from the soil, sand and brick samples which were collected from the selected area. Effect of moisture contents on the radon exhalation rate using a closed can technique has also been presented in the chapter. The effect of back diffusion on the radon exhalation has also been studied and included in this chapter. Measurement of the natural radioactivity in the soil and other building materials, 1like sand, brick, marble and cement samples which were collected form the selected area has been dealt with in chapter 6. Research work performed at the University of St., John University USA has been included in chapter 7 and 8. These chapters include experiments performed in the exposure room using the electret ion chambers. Radon concentration in the exposure room was measured using both short term and long term electrets. It also includes the results of the performance factor for the alpha contamination chambers using the electrets as radon progeny dosimeter. Experiments were performed using both short term high sensitivity and long term (low sensitivity) electrets. Development of a new passive thoron progeny dosimeter using the principle of the surface deposition has been discussed in chapter 8. This chapter includes an introduction about the different types of active and passive equipments used for the measurement of thoron. It also discusses the calibrations of different types of active detectors for the measurements of surface deposited activities on the glass surfaces. Finally chapter 9 concludes the present research work and includes future recommendations.
