Although Imam Qusṭalānī, in compiling his book "Al-Mawāhib Al-Laduniyat Bil Minḥ Al-Muhammadiyah", has followed the footsteps of Qazi Ayaz’s book Al- Shifā. But many chapters and information are unique to them and he has expanded this book with his additions and made it a treasure trove of information. This book is a beautiful fusion of the traditions of Muhaddithin and Ahl-e-Siyyar. Because he was not only a muhaddith but also a biographer. Were his greatest service in the learning of Hadith is "Irshad Al-Sārī Sharh Saḥiḥ Bukhārī", there his most significant service in Sira is this book. He has used the traditions of both the narrators and the Biographers in compiling it. In this book, the locks of meanings are opened with the keys of Fatḥ Al-Bārī Li Ibn-e-Hajar ‘Asqalānī. In other words, he has benefited a lot from Fatḥ Al-Bārī Sharḥ Bukhari and has gained a lot of confidence. A large number of scholars have used this book, including Shiblī Nu‘mānī, who has made extensive use of it in his Sirat un-Nabiﷺ . Due to its popularity, many of its rates have been written. The most detailed of these is the Zurqānī rate of Qusṭalānī. The great scholar like Imam Zarqani has commented in eleven volumes of this book, which is proof of its authenticity, noteworthy, and worth reading and treasure. Sheikh Nūruddin Ṭrabulsī gave Sharh and great people like Safiuddin Qasashi, Burhanuddin Ibrahim Maimoni, Shamsuddin Muhammad Shobri Misri and Nooruddin Ali Qari embellished this book with their footnotes. On the one hand, it teaches love and respect for the Holy Prophet ﷺ and on the other hand, it mentions the rights of the Holy Prophet ﷺ and the rewards for their payment. The writing style of the book is simple and smooth as well as eloquent and eloquent. The temptation is not so long that the length will be too long for the reader, nor is it so short that access to the concepts and demands will not be possible due to the brevity. The book has been read by the people and it has been adopted by biographers as an authentic and reliable source. Because of its importance and usefulness, an introductory and analytical study of this book will be presented in this article.

Catalytic Studies of Butadiene/Ethylene Polymerization

In present study, the polymerization of butadiene and ethylene were carried out using heterogeneous monometallic, bi-and tri-metallic catalysts. Five types of catalysts, nickel, cobalt monometallic, Ni-Co bi-metallic, and Ni-Co-Pd, Ni-Co-Pt tri-metallic were synthesized by using sol-gel, impregnation and hydrometallurgical methods. The synthesized nano composites were subjected to calcinations at 200, 400, 600 and 900 oC, to study their effects on catalyst morphology, activity and product selectivity. These were characterized by X-ray diffraction (XRD), helium adsorption Brunaur, Emmett and Teller (BET), scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectrometer (EDX), transmission electron microscopy (TEM), FT-IR Spectroscopy, temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and X-ray Photoelectron spectroscopic (XPS) studies. The synthesized catalysts were tested for the polymerization of butadiene and ethylene in ethanol, n-hexane and toluene solvents at various temperature and pressure conditions in Parr reactor. The products obtained were characterized by Fourier transform infrared spectroscopy FT-IR, 1H and 13 C Nuclear magnetic resonance spectroscopy (NMR), Gel permeation chromatography (GPC), Thermogravimetric analysis (TGA), Static laser light scattering (SLLS) and Mass spectrometric analysis (MS). The results showed that in ethanol solvent at 130 °C and 1.0 barr pressure, the product obtained consists of aliphatic and aromatic carbonyl compounds and polybutadiene terminated by -OH group. The selectivity of product was obtained in n-hexane and toluene solvent. In order to synthesize hydroxyl group terminated polybutadiene HTPB, the termination of polybutadiene was carried out by acidic solution of ethanol or hydrogen peroxide, whereas the termination of polyethylene was carried out by the acidic solution of ethanol. The significant product was achieved with the catalyst prepared by hydrometallurgical method as compared to other techniques. The best results were achieved with the Ni-Co- Pt catalyst calcined at 900 oC with molecular weight average of 12414 and a polydispersity Mw/Mn value of 1.404 under controlled conditions of temperature 130 oC and pressure 1.0 barr. The microstructure distribution of polybutadiene was studied by carrying out catalytic activity test at different temperature and pressure conditions. 100% stereoregular product of cis-1,4 polybutadiene have been achieved at low temperature 30 oC and pressure 0.5 barr with the catalyst Ni-Co calcined at 900 oC.
