from your hand, Satan will seize it; he does not seize it while we are looking, for this belongs to the realm of the unseen that we cannot perceive. We know it only from the report of the ever-truthful, trusted Messenger ﷺ: Satan takes the fallen morsel and eats it, even though to our physical sight it is still lying in front of us. He eats it in the unseen world, and such unseen matters are ones we are obliged to affirm.
Yet the Messenger of Allah ﷺ directed us to what is good, saying, “Let him pick it up, remove whatever dirt is on it, and eat it; do not leave it for Satan.” So pick it up, brush off any filth—dust, bits of wood, or the like—then eat it and do not hand it over to Satan. Whoever does this in obedience to the Prophet ﷺ, in humility before Allah, and in order to deprive Satan of it attains three benefits: compliance with the Prophet’s command, cultivation of humility, and preventing Satan from eating it. These three benefits are there, yet most people, when a morsel falls on the tablecloth or on a clean mat, simply leave it—contrary to the sunnah.
Another lesson within this hadith is that one should not eat food that contains anything harmful, for your own self is a trust with you. Do not eat anything that might injure you—sticks, thorns, and the like. We therefore remind those who eat fish to be cautious, because fish contain fine bones like needles; if a person is not careful, a bone may slip into the stomach and cut the stomach or intestines without his even realizing it. A person must look after himself and be the best guardian of his own well-being.
So may Allah’s blessings and peace be upon our Prophet Muhammad, his family, his Companions, and all who follow them with excellence until the Day of Judgment.
