صحيح مسلم 4279

Tamim b. Tarafa reported that he heard 'Adi b. Hatim say that a person came to him and asked for one hundred dirhams. He ('Adi) said:You asked me for one hundred dirhams and I am the son of Hatim; by Allah, I will not give you. But then he said: (I would have done that) if I had not heard Allah's Messenger (ﷺ) say: He who takes an oath, but then finds something better than that, should do that which is better

Rapporté par Tamim ibn Tarafa : Il a entendu ‘Adi ibn Hatim dire qu’un homme est venu lui demander cent dirhams. ‘Adi a dit : « Tu me demandes cent dirhams alors que je suis le fils de Hatim ; par Allah, je ne te donnerai rien. » Mais il a ajouté : « Je l’aurais fait si je n’avais pas entendu le Messager d’Allah ﷺ dire : “Celui qui fait un serment et trouve ensuite quelque chose de mieux doit faire ce qui est mieux.” »
