Musnad Ahmad 937:145

He said: Shu'bah narrated to us, from Sulayman, from Zayd ibn Wahb, from Abu Dharr, from the Prophet, may Allah bless him and grant him peace, that he said: "Gabriel gave me glad tidings that whoever among your nation dies not associating anything with Allah will enter Paradise." I said: "Even if he committed adultery and even if he stole?" He said: "Even if he committed adultery and even if he stole."
