Musnad Ahmad 1153:1253

'Affan narrated to us, Hammam narrated to us, he said: I heard Ishaq bin 'Abdullah bin Abi Talha, he said: Shaybah al-Khudari narrated to me that he witnessed 'Urwah narrating to 'Umar bin 'Abd al-'Aziz, from 'Aishah, that the Prophet (peace and blessings of Allah be upon him) said: "Allah, the Almighty and Majestic, does not make a man who has a share in Islam like one who has no share in it." He said: "And the shares of Islam are: fasting, prayer, and charity. And Allah, the Almighty and Majestic, does not take charge of a man in this world, then entrust him to someone else 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." He said: "And the fourth: Allah, the Almighty and Majestic, does not conceal a sin for a servant except that He will conceal it for him in the Hereafter." He said: So 'Umar bin 'Abd al-'Aziz said: "When you hear a hadith like this from someone like 'Urwah, from 'Aishah, from the Prophet (peace and blessings of Allah be upon him), then preserve it."
