Musnad Ahmad 1153:370

Hassan and Yahya ibn Ishaq narrated to us, they said: Ibn Lahi'ah narrated to us, he said: Khalid ibn Abi 'Imran narrated to us, from al-Qasim ibn Muhammad, from 'Aishah, from the Messenger of Allah, may Allah bless him and grant him peace, that he said: "Do you know who are the first to reach the shade of Allah, the Almighty and Majestic, on the Day of Resurrection?" They said: "Allah and His Messenger know best." He said: "Those who, when the truth is given to them, they accept it; and when they are asked for it, they offer it; and they judge for the people as they judge for themselves."
