Sistem baru jual beli online yang lebih digemari di kalangan masyarakat adalah COD (Cash on Delivery). Akan tetapi dalam pelaksanaan jual beli secara online berbasis COD tidak semuanya sah secara hukum dikarenakan beberapa pelaku usaha gemar melakukan penipuan atau pemalsuan informasi, salah satunya adalah ketidaksesuaian informasi barang dengan bentuk barang yang diterima. Penelitian ini membahas tentang jual beli online dan implementasi asas itikad baik di dalam suatu transaksi jual beli online, dengan tujuan untuk memahamkan asas itikad baik kepada masyarakat luas dalam pengaplikasiannya pada transaksi jual beli online. Penelitian ini menggunakan metode kualitatif kepustakaan. Hasil penelitian ini, ditemukan bahwasanya pengimplementasian asas itikad baik di dalam transaksi jual beli online dapat diterapkan oleh penjual dengan cara memberikan informasi tentang barang yang dijualnya dengan jujur, dan pembeli dengan cara membayarkan sejumlah uang sesuai dengan kesepakatan di awal perjanjian, sehingga keduanya akan sama-sama diuntungkan oleh transaksi ini. Selain itu penting untuk marketplace  agar memperbaiki sistem  yang digunakannya untuk menjadi situs web jual beli online sebagai salah satu bukti itikad baik yang ditujukan kepada pelaku usaha dan pembeli. Maka perlu bagi marketplace, pelaku usaha, dan juga pembeli untuk menerapkan asas itikad baik sehingga tidak ada pihak yang mungkin akan dirugikan.

This study aims to describe and analyze the basic concepts and concepts of justice in Islamic inheritance law to answer the contradictory concepts brought by Islamic modernist thinkers such as Asghar Ali Engineer and Zaitunah Subhan. To achieve this goal, the author uses a qualitative-descriptive-library research method. The conclusion obtained, the concept of justice in Islamic inheritance is the consistency of giving inheritance rights to heirs who are entitled without any disparity between gender or age. All have inheritance rights with three categories, namely the definite part (fardl), soft (ta'shib), and hindered (hijb). So, the assumption by some people that Islamic inheritance law based on the Qur'an is not in line with the principle of justice is a completely baseless accusation. Justice in Islam does not mean equality or adjustment to the conditions and realities of the times. Justice in Islam is more universal for the survival of all human beings on the instructions of Allah Swt.

As a country with the largest muslim population in the world, Indonesia is still far behind in developing the potential of zakat, infaq, sadaqa, and waqf (ziswaf) which should be optimized. This requires a mature strategy in managing to maximize the potential of ziswaf. This study aims to examine the development of ziswaf strategic management at the Baitul Al-Qur'an Social Fund Institution (LDSBQ) which has a vision and mission based on Islamic sharia and aims to prosper the Ummah. This research uses a qualitative approach with a descriptive analysis method, while the data collection instruments use interviews, observation, and documentation. Sources were taken from various references related to the topic of the problem, namely journals, books, and other articles. The results showed that the three main programs of LDSBQ are First, scholar smile; engaged in education. Second, smile healthy; is engaged in the health sector. Third, independence smile; which is a movement for community independence in the economic field, and is supported by social-religious activities such as waqf and da'wah programs. While the fundraising strategy uses a potential network of student and teacher guardians, a network of Gontor alumni colleagues, program socialization through social media, online and offline donation services, and program-based waqf. With a real sector-based movement, social community activities can have a significant impact on the welfare of the ummah to gain happiness in this world and the hereafter.
