Musnad Abu Ya'la al-Mawsili 150:62

Hadaba ibn Khalid narrated to us, Hammam narrated to us, from Ishaq ibn Abdullah ibn Abi Talha, from Shaybah al-Khudari, that he witnessed Urwah narrating to Umar ibn Abd al-Aziz, from Aisha, from the Prophet, peace and blessings of Allah be upon him, who said: "Three things I swear upon: Allah does not make the one who has a share in Islam like the one who has no share. The shares of Islam are three: fasting, prayer, and charity. Allah does not take charge of a servant and then entrust him to another on the Day of Resurrection. And a man does not love a people except that he will come with them on the Day of Resurrection. And the fourth, if I were to swear upon it, I would not fear that I have sinned: Allah does not conceal [the sins of] His servant in the world except that He will conceal him on the Day of Resurrection." Umar ibn Abd al-Aziz then said: "If you hear the likes of this from the likes of Urwah, then memorize it."
