Musnad Ahmad 1550
Musnad Abu Ishaq Sa'd bin Abi Waqqas
It was narrated from Malik bin Aws: I heard "Umar say to ‘Abdur-Rahman bin ‘Awf, Talhah, az-Zubair and Sa"d: I adjure you by Allah, by whose power heaven and earth exist - on one occasion he said: by Whose leave heaven and earth exist - do you know that the Messenger of Allah (ﷺ) said: "We [Prophets(ﷺ)) are not to be inherited from; what we leave behind is charity”? They said: By Allah, yes.
