Islamic law is a law based on the Qur'an, hadith, qiyat and ijma'. In essence, Islamic law is used as the basis of life and solutions to human problems. However, at present, the diversity of problems faced by humans makes Islamic law seem rigid and too binding. This paper will explain the concept of Ijtihad by Ibn Taimiyah in the context of reforming Islamic law. This research is in the form of library research through content analysis techniques. The main sources used by Ibn Taimiyah in performing ijtihad are the Qur'an and hadiths. He never put reason as a basis for thinking because for him reason is weak and weakens belief in the religion of Allah. In addition, he carried out Ijtihad by providing comparisons between existing schools and trying not to influence anyone because the method of ijtihad he did was ijtihad independently. The results of ijtihad produced by Ibn Taimiyah which are currently used are the requirements for the implementation of prostration and recitation as well as the exchange of unproductive waqf assets.Keywords: Islamic Law; Ibnu Taimiyah; Ijtihad

The purpose of this study is to find out how reason and revelation go hand in hand in the formation of Islamic law. The method used is a literature study with a qualitative approach. The results of the study show that reason and revelation are both the basis for giving birth to Islamic law. This study also analyzes that there is no contradiction between reason and revelation in principle. In fact, the position between reason and revelation can be parallel, but theologically it is revelation that is the source of inspiration for reason so that revelation (as a subject) has a higher position. On the other hand, reason cannot be a source of revelation, because reason is a creation while revelation is the word of God. The conclusion of this research is that today's Islamic law must be able to maximize its scientific reasoning (reasoning) in order to find hidden meanings in the texts of the Qur'an and hadith in answering the problems of life in the world without neglecting the benefits of the hereafter.

This research was conducted with the aim to explain the law of fasting during the Covid-19 pandemic upon those who are Covid-19 positive, those who were Covid-19 positive yet asymptomatic, and health workers who treat Covid-19 patients. This research used a qualitative approach using content analysis and library research. The results showed that, first, people who are Covid-19 positive are considered sick so that they have excuse to break the fasting; Second, those who are Covid-19 positive but show no symptoms are considered sick people so that they may not fast; Third, those who are still healthy and have not been infected with Covid-19 and have met the conditions of fasting and have no excuse that prevent them from fasting then it is obligatory upon them to fast; Fourth, medical workers who treat Covid-19 patients are still required to fast. If in conducting their duties they are very thirsty, hungry, or exhausted who are feared to be vulnerable to falling ill and be infected with Covid-19, then they may break their fast.
