Is the door of Ijtihad open or closed?

Q 5: Is it permissible in these days to practice Ijtihad (juristic effort to infer expert legal rulings)?

A: All praise be to Allah Alone and peace and blessings be upon His Messenger, his family and Companions. To commence, practicing Ijtihad is still opened before people of knowledge and belief who have deep insight and understanding for the Qur'an, the Sunnah of the Messenger of Allah (peace be upon him) and the sayings of those who preceded us from among the Companions of the Prophet (peace be upon him) and those who followed them in righteousness from among scholars. Whoever can not do so should ask the people of knowledge as was mentioned earlier. (Part No. 5; Page No. 15) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
