1؎: That is, remove the dust that has settled on the fallen morsel, appreciate this blessing of Allah, and eat it; do not leave it for Shaytan, because leaving it would be showing ingratitude for this blessing. However, it should also be considered that the morsel should not have fallen in a place that is impure or filthy. If that is the case, then it is better to clean it and feed it to an animal.

Explanation: 1: That is, the dust or dirt that has settled on the fallen morsel should be removed, so that one appreciates this blessing of Allah, and eats it, not leaving it for Shaytan, because leaving it would be showing ingratitude for this blessing. However, it should also be considered that the morsel has not fallen in a place that is impure or filthy; if that is the case, then it is better to clean it and feed it to an animal.

´It was narrated from Jabir that the Messenger of Allah (ﷺ) said:` “None of you should wipe his hand until he has licked it, for he does not know where the blessing if in his food.’”
Maulana Ataullah Sajid
Benefits and Issues:
➊ After eating, one should clean the fingers with the tongue.
➋ Wasting even a small portion of food is ingratitude for the blessing.
➌ It is not appropriate to wipe the hand with a cloth or wash it with water without first cleaning it, because in this way the cloth will be soiled or water will be used more than necessary, and the food particles stuck to the hand will go into the bread, which is a form of disrespect for the blessing of sustenance.
➍ Blessing (barakah) is an intangible and imperceptible thing. For its attainment, one should act upon the teachings of the Prophet (sallallahu alayhi wa sallam) and avoid wasting sustenance.
➎ Letting someone else lick (the fingers) is permissible when the other person does not feel any aversion to it, for example: a wife or children, etc.
