It is not in legislation alone, but in all aspects of social life. This renewal means the flexibility of the mind to replace old conditions with new ones, or to modify the new to be compatible with the old. Sheikh Muhammad Abduh was asked new questions that jurists had not previously addressed because the environment created them anew, such as reading the Quran on the radio, not wearing a turban, life insurance, and creating money in savings accounts, and so on, which were not known before. Jean-Jacques Rousseau defined renewal as "adopting humanitarian principles, rational principles, and philosophical tolerance, and replacing old conditions, the sanctification of authorities, and narrow-minded fanaticism with them." Renewal is in each case according to its circumstances. Proponents of renewal may find themselves facing two contradictory currents, forcing them to confront both, as happened in our era with the doctrine of socialism. Its proponents saw themselves as compelled to confront the extreme idea of communism and the rigid idea of capitalism. The idea of renewal is aided by the peoples' feeling of their bad condition and their ambition for a better condition than their current one and a better system than their current one.
