Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: When a ruler makes a judgment through ijtihad (striving) and is correct, he receives two rewards, and when a ruler makes a judgment through ijtihad but it is incorrect, he still receives one reward. Abu Muhammad says: We do not know that anyone other than Mu’ammar has narrated this hadith from Thawri.
