It never happened that Allah's Messenger (ﷺ) was asked for anything and he said: No.

It never happened that Allah's Messenger (ﷺ) was asked anything for the sake of Islam and he did not give that. There came to him a person and he gave him a large flock (of sheep and goats) and he went back to his people and said: My people, embrace Islam, for Muhammad gives so much charity as if he has no fear of want.

(By Allah) Allah's Messenger (ﷺ) gave me what he gave me (and my state of mind at that time was) that he was the most detested person amongst people in my eyes. But he continued giving to me until now he is the dearest of people to me.

In case we get wealth from Bahrain, I would give you so much and so much; he made an indication of it with both his hands. Allah's Apostle (ﷺ) died before wealth from Bahrain came, and it fell to the lot of Abu Bakr after him. He commanded the announcer to make announcement to the effect that he to whom Allah's Apostle (ﷺ) had held out promise or owed any debt should come (to him). I came and said: Allah's Apostle (ﷺ) had said to me: In case there comes to us the wealth of Bahrain I shall give you so much, and so much. Abu Bakr took a handful (of the coins) and gave that to me once and asked me to count them I counted them as five hundred dinars and he said: Here is double of this for you.
