The Prophet ﷺ said, "All flying insects are in the Fire except the bee." He used to forbid killing them, and he also forbade the burning of food.Sufyan remarked, "It seems that the burning of food refers to doing so in enemy territory."
عن النبي ﷺ قال: الذباب كله في النار إلا النحلة وكان ينهى عن قتلهن، وعن إحراق الطعام. قال سفيان: يشبه أن يكون إحراق الطعام في أرض العدو.
Tabarani related it in Al-Kabir (12/389) and in Al-Awsat (1575) via Muhammad bin Ammar Mawsili, who said, "Qasim bin Yazid Jarmi narrated to us, who said, Sufyan Thawri narrated to us, from Mansur, from Mujahid, from Ubayd bin Umayr Laythi, from Ibn Umar," and he related it.Tabarani said, "No one narrated this hadith from Sufyan except Qasim, and Muhammad bin Ammar transmitted it alone." Its chain is sahih, all its narrators being trustworthy. Muhammad bin Ammar is named after his grandfather, being Muhammad bin Abdullah bin Ammar, Abu Jafar Baghdadi, who settled in Mosul, a trustworthy and precise memorizer.Haythami said in Al-Majma (4/41), "Tabarani related it in Al-Awsat and Al-Kabir through chains, the narrators of some of which are all trustworthy."A note of caution, Ibn Jawzi included it in Al-Mawduat (3/265) and faulted it because of Qasim bin Yazid, saying, "He is unknown." This is a gross error, and Dhahabi therefore took him to task for it in his summary of Al-Mawduat, saying, "This is a sound chain, so what business does this have here?"
