Abu Thawr reported,

Uthman sent Saeed bin al-As on the day of al-Jaraa. The people went out to confront him and turned him back.I was sitting with Abu Masud and Huzaifa, and Abu Masud said, "I never thought he would return without blood being shed over him."Huzaifa replied, "But I know for certain that they will turn back without a single cupping vessel of blood being spilled. I knew everything about this while Muhammad ﷺ was still alive. Indeed, a man may rise in the morning a believer and reach the evening with nothing of faith left in him, and he may reach the evening a believer and rise in the morning with nothing of it left. He fights for his faction today, and Allah kills him tomorrow. His heart is turned upside down, his backside rising above it."I asked, "His underside?"He said, "His backside."

عن أبي ثور قال

بعث عثمان يوم الجرعة بسعيد بن العاص قال: فخرجوا إليه، فردوه، قال: فكنت قاعدا مع أبي مسعود وحذيفة، فقال أبو مسعود: ما كنت أرى أن يرجع لم يشرق فيه دما، قال: فقال حذيفة: ولكن قد علمت لترجعن على عقيبها لم يهرق فيها. محجمة دم، وما علمت من ذلك شيئا إلا علمته، و محمد ﷺ حى، حتى إن الرجل ليصبح مؤمنا ثم يمسي ما معه منه شيء، ويمسي مؤمنا ويصبح ما معه منه شيء، يقاتل فئته اليوم، ويقتله الله غدا، ينكس قلبه تعلوه استه. قال: فقلت: أسفله؟ قال: استه.
