Can The Definition Of ( الصَّالِحُونَ) In Nisai (5401) Be Extended Beyond Sahabah?
Only Hujjat for us are Quran and Sunnah, which are transmitted to us through ijma of Sahaba. But as far as ijtihaad is concerned, it is by definition not a hujjat on anyone, whether it be ijtihaad of Sahaba or later imams. Each and every ijtihaad needs to be reviewed and revised if another ijtihaad fits better within overall framework of Quran and Sunnah and is more logical given the current circumstances. However, ijtihad of Sahaba and later imams need to be reviewed carefully and in-depth before dismissing it altogether.
