"I attended the assembly of 'Umar Radiyallahu 'Anhu, At that time 'Abdurrahmaan bin 'Awf Radiyallahu 'Anhu and Sa'd bin Abi Waqqaas Radiyallahu 'Anhu were also present. (After a little while) 'Abbaas Radiyaalhu 'Anhu and Ali Radiyallahu 'Anhu came to solve a disagreement. 'Umar Radiyallhu 'Anhu said to them: 'I swear an oath by the One with whose command the skies and earth function, and I ask you, do you know of the saying of Rasulullah Sallallhu 'Alayhi Wasallam that we (the ambiyaa-prophets), do not make anybody our heirs. Whatever wealth we leave behind, is all left as sadaqah'. All those present replied: 'Verily true'. This hadith has a long story".
