Al-Dahhak bin Muzahim (may Allah have mercy on him) narrates that I, Tawus al-Yamani (may Allah have mercy on him), Amr bin Dinar al-Makki (may Allah have mercy on him), Makhul al-Shami (may Allah have mercy on him) and al-Hasan al-Basri (may Allah have mercy on him) gathered in Masjid al-Khayf. Then we began discussing the question of divine decree (qadar), until our voices were raised and the clamour increased. At this Tawus (may Allah have mercy on him) stood up and said: "Be silent, I will tell you what I heard from Sayyiduna Abu al-Darda' (may Allah be pleased with him); he used to narrate from the Messenger of Allah (peace and blessings be upon him) that the Messenger of Allah (peace and blessings be upon him) said: 'Indeed, Allah Almighty has made certain obligations binding on you, so do not neglect them. He has set certain limits for you, so do not transgress them. He has forbidden you certain things, so do not violate their sanctity. And He has remained silent about certain things, not out of forgetfulness (but purely as mercy), so do not burden yourselves with probing into them; this is a mercy from your Lord, so accept it. All matters are in the hand of Allah; their origin is from Allah and their return is to Him. The servants have neither complete authority (tafwid) in them nor an independent will.'"
Then all the people got up, content with what Tawus (may Allah have mercy on him) had said.
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu al-Darda' (may Allah be pleased with him) only with this chain; Asad bin Musa is alone in narrating it."
