SUMMARY
The ultimate purpose of Sharia law is to protect the welfare of humans by bringing benefits for them and preventing harms from them. The jurists agree that the evidence of maslahah is the basis on which the provisions of financial and banking transactions are based regardless of their difference of opinions in terms of its conditions. The reality of Islamic banking transactions and the complexity of many of its issues make the existence of clear evidence from the Quran and Sunnah difficult, which necessitates for the researchers to make additional efforts in this field, and conduct ijtihad to use the evidence of maslahah with its legal conditions as a way to reveal the Shari`ah rulings by following the Companions and righteous scholars during their time. Therefore, the research will deal with the concept of maslahah and some issues related to considering it in financing with al-Qar? al-?asan in the Islamic banks, and opinions of scholars about it. In addition, it explains the procedures of granting al-Qar? al-?asan at Al Baraka Islamic Bank in Algeria and highlights the need of the Algerian youth to obtain al-Qar? al-?asan which will be investigated through the distribution of questionnaires among them. The research follows the inductive approach to extrapolate the scholars' opinions, and analytic approach to analyze their views, and analyze the results of the questionnaires about al-Qar? al-?asan. The research concludes that the Shari`ah ruling of some issues of al-Qar? al-?asan is based on evidence of maslahah including all of its types which are considered, canceled and silenced ones.Keywords: Interest, Financing, al-Qar? al-?asan, Islamic Banks, Al Baraka Bank of Algeria.
