Musnad Ahmad 1153:1103

Yazid narrated to us, Hammam ibn Yahya informed us, from Ishaq ibn Abdullah ibn Abi Talha, who said: Shaybah al-Khudri narrated to me, saying: We were with Umar ibn Abd al-Aziz, and Urwah ibn al-Zubayr narrated to us, from Aisha, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Three things I swear upon: Allah, the Almighty and Majestic, does not make the one who has a share in Islam like the one who has no share. The shares of Islam are three: prayer, fasting, and zakat. And Allah, the Almighty and Majestic, does not take charge of a servant in this world but that He will entrust him to someone else on the Day of Resurrection. And no man loves a people but that Allah, the Almighty and Majestic, will place him with them. And the fourth, if I were to swear upon it, I would hope not to be sinful: Allah, the Almighty and Majestic, does not conceal a servant in this world but that He will conceal him on the Day of Resurrection." Umar ibn Abd al-Aziz said: "When you hear a hadith like this from someone like Urwah, narrating it from Aisha, from the Prophet (peace and blessings of Allah be upon him), then memorize it."
