Musnad Ahmad 1153:389

Ishaq ibn Isa narrated to us, he said: Ibn Lahi'ah narrated to us, and Yahya ibn Ishaq said: Ibn Lahi'ah informed us, from Khalid ibn Abi Imran, from al-Qasim ibn Muhammad, from Aisha, who said: The Messenger of Allah (peace and blessings of Allah be upon him) 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, the Almighty and Majestic, 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."
