It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah Almighty: "We will surely cause him to live a good life." [Surah al-Nahl: 97] He said: "It means contentment." And (he further said that) the Messenger of Allah (peace and blessings be upon him) used to make this supplication: 'Allahumma qanni'ni bima razaqtani, wa barik li fihi, wakhluf 'alayya kulla gha'ibatin li bikhayr' (O Allah, make me content with the provision You have given me, bless it for me, and replace for me with something better everything of mine that is hidden (lost))." The chain of this hadith is sahih (authentic).
