Hadith Commentary:
This was the extent of your (the Prophet’s) magnanimity; in fact, if you had it (the item requested), you would give it at that very moment, otherwise you would promise the person that soon you would give it to him—sallallahu alayhi wa sallam. And it does not necessarily follow from this that you would never offer an excuse, as is found in His statement, the Exalted: “Say: I do not find anything upon which to mount you” ().
That is, it does not follow from this that in the case of not having something, you would not even offer an excuse, as in the aforementioned verse where, on one occasion, you said to some people that at that moment you did not have an animal for them to ride.

Hadith Commentary:
Whenever worldly wealth or possessions were requested from the Messenger of Allah (sallallahu alayhi wa sallam), he did not refuse to give. If he did not have anything, he would remain silent. If there was hope of obtaining it soon or later, he would intend to give it.

Benefit:
In this hadith, the generosity of the Messenger of Allah (sallallahu alayhi wa sallam) is mentioned, that he (sallallahu alayhi wa sallam) would not send back any person who asked him empty-handed.
