Ketentuan Masa ‘Iddah Wanita Hamil Yang Diceraikan Qobla Dukhul Menurut Mazhab Hanafi dan Syafi’i
No full textThis study aims to protect and prevent the author, especially Muslims in general, from falling into the practices prohibited by Islam and to be able to understand the \u27iddah regulations for divorced pregnant women to find out when the qobla dukhul occurred, which in this case the author is from the Hanafi school From the perspective of Shafiyi. The reason why the author only gives the views of the Hanafi and Shafi’i schools is that only these two schools believe that women who become pregnant through adultery can marry without waiting for the birth of a child. Her fetus. The research method used in this work is a qualitative method, which belongs to the type of library research (library research). Research analysis shows that Islam is a perfect religion and Allah has ordained everything that is good for the servant. An example in this case is how Islam strictly forbids adultery among its people, this is for the protection of Maqasid Sharia, one of which is to protect future generations. Also, the period of \u27iddah for a pregnant woman divorced from Qobla Dukhul is determined according to the Hanafi and Syafi\u27i schools, so in this case the two schools of thought differ in the meaning of Qobla Dukhul, which may have legal implications. Therefore, the two schools of thought hardly differ in their determination.Keywords: The period of \u27Iddah; Qobla Dukhul; Hanafi; Shafi\u27i AbstrakPenelitian ini bertujuan untuk menjaga dan mencegah diri penulis secara khusus dan kaum muslimin secara umum agar tidak terjatuh pada perbuatan yang diharamkan oleh Islam serta dapat mengetahui ketentuan ‘iddah wanita hamil yang diceraikan apabila terjadi qobla dukhul, yang dalam hal ini penulis ambil dari perspektif mazhab Hanafi dan Syafi’i. Adapun alasan penulis hanya mencukupkan perspektif mazhab Hanafi dan Syafi’i adalah karena hanya kedua mazhab inilah yang memandang bahwa wanita yang hamil karena sebab zina maka ia boleh dinikahi tanpa harus menunggu lahirnya janin yang ia kandung. Metode penelitian yang digunakan dalam skripsi ini adalah metode Kualitatif, dengan jenis penelitian kepustakaan (Library Research). Analisa penelitian menunjukkan bahwa Islam adalah agama yang sempurna, sehingga segala hal yang merupakan hal baik bagi seoang hamba menurut Allah telah diatur dengan sedemikian rupa. Sebagai contoh dalam hal ini adalah bagaimana Islam itu melarang keras ummatnya melakukan zina, hal ini untuk menjaga maqashid syari’ah yang mana salah satunya adalah untuk menjaga keturunan. Begitu pula tentang penentuan masa ‘iddah wanita hamil yang diceraikan qobla dukhul menurut mazhab Hanafi dan Syafi’i, maka dalam hal ini kedua mazhab tersebut berbeda pandangan dalam maksud dari qobla dukhul yang dapat berimplikasi hukum, sehingga dalam penentuannya ada sedikit perbedaan pandangan antara kedua mazhab tersebut.Kata kunci: Masa ‘Iddah; Qobla Dukhul; Hanafi; Syafi’
A Glimpse into the Scholarly Works of Sheikh Muhammad Hayat Sindhi
No full textSindh is considered to be the first region of the subcontinent where the light of Islam illuminated the land.This region has produced numerous scholars who gained renown throughout the Islamic world. Among these luminaries was Sheikh Muhammad Hayat bin Ibrahim Sindhi (d. 1163 A.H.), a prominent Islamic scholar, jurist, and prolific author affiliated with the Hanafi School of jurisprudence. Sheikh Hayat Sindhi was celebrated as one of the leading experts in Hadith, jurisprudence, and various other Islamic disciplines, including Islamic literature. Born in Sindh, Sheikh Hayat Sindhi received his early education from his father. He later traveled to Thatta, where he studied under renowned scholars such as Muhammad MoinThattavi. Seeking advanced knowledge in Islamic disciplines, he migrated to theHaramainSharifain, andeventually settled in Madinah.There he began teaching at Masjid al-Nabawi and dedicated himself to teaching hadith for 24 years. Sheikh Hayat Sindhi authored numerous books on diverse topics related to Islamic studies and the social issues facing Muslim societies. His works, renowned among Islamic scholars, are imbued with wisdom, etiquette, and ethical values derived from the Qur’an, Hadith, jurisprudential insights of eminent scholars, and intellectual reasoning. This study provides a concise biography of Sheikh Hayat Sindhi and examines his contributions across various fields of Islamic knowledge. It also reflects an admiration and appreciation for the profound impact of his scholarly works
Comparative analysis of alternative fuels in detonation combustion
No full textDetonation combustion prominently exhibits high thermodynamic efficiency which leads to better performance. As compared to the conventionally used isobaric heat addition in a Brayton cycle combustor, detonation uses a novel isochoric Humphrey cycle which utilises shocks and detonation waves to provide pressure-rise combustion. Such unsteady combustion has already been explored in wave rotor, pulse detonation engine and rotating detonation engine configurations as alternative technologies for the next generation of the aerospace propulsion systems. However, in addition to the better performance that the detonation mode of combustion offers, it is crucial to observe the environmental concerns as well. Therefore, this paper presents a one-dimensional numerical analysis for alternative fuels: Jet-A, Acetylene, Jatropha Bio-synthetic Paraffinic Kerosene, Camelina Bio-synthetic Paraffinic Kerosene, Algae Biofuel, and Microalgae Biofuel under detonation combustion conditions. For simplicity, the analysis is modelled using an open tube geometry. The analysis employs the Rankine-Hugoniot Equation, Rayleigh Line Equation, and Zel’dovich–von Neumann–Doering model and takes into account species mole, mass fraction, and
enthalpies-of-formation of the reactants. Initially, minimum conditions for the detonation of each fuel are determined. Pressure, temperature, and density ratios at each stage of the combustion tube for different types of fuel are then explored systematically. Finally, the
influence of different initial conditions is numerically examined to make a comparison for these fuels
Investigation of three-shaft high-bypass-ratio engine performance and emission prediction using alternative fuels
No full textProtecting the environment has become the main challenge in recent years specifically in aviation industries as they lead to the vulnerable energy crisis and simultaneously pose environmental concerns. With the stringent policies and legislations applied, many potential technological advancement programs are well planned and found out drop-in alternative fuels can potentially help to meet the target. In response, the purpose of this research aims to numerically evaluate the feasibility of the alternative fuels in terms of performance for a conventional aero-gas turbine engine. The investigated contents encompass the evaluation of engine performance analysis and emission prediction analysis. This research served as an extension of the PhD work of the principle investigator. Engine performance analysis utilizes a Cranfield Univeristy in-house latest code version of PYTHIA for modeling a three-shaft high-bypass-ratio engine which is similar to RB211 variant at various off-design conditions. Focusing on NOx formation, the emission analysis was also carried out using a Cranfield University in-house HEPHAESTUS emission model prediction. Alternative fuels are expected to show much better engine performance with further reductions in NOx emission. Finally, the research brings together all the analyses and makes trade-offs assessment between the performance and emission by applying a Design of Experiment (DoE) method, to identify the factors main effects, their interactions and the best trade-off solutions
