حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ، قَالَ حَدَّثَنِي عُتْبَةُ بْنُ مُسْلِمٍ، قَالَ أَخْبَرَنِي عُبَيْدُ بْنُ حُنَيْنٍ، قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ يَقُولُ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ إِذَا وَقَعَ الذُّبَابُ فِي شَرَابِ أَحَدِكُمْ فَلْيَغْمِسْهُ، ثُمَّ لِيَنْزِعْهُ، فَإِنَّ فِي إِحْدَى جَنَاحَيْهِ دَاءً وَالأُخْرَى شِفَاءً ‏"‏‏.‏
Translation
Narrated Abu Huraira

The Prophet (ﷺ) said "If a house fly falls in the drink of anyone of you, he should dip it (in the drink) and take it out, for one of its wings has a disease and the other has the cure for the disease."

Comment

Beginning of Creation - Sahih al-Bukhari 3320

The Prophet (ﷺ) said "If a house fly falls in the drink of anyone of you, he should dip it (in the drink) and take it out, for one of its wings has a disease and the other has the cure for the disease."

Scholarly Commentary

This hadith contains profound wisdom that modern science has only recently verified. The command to dip the fly completely before removing it indicates that when submerged, the fly releases antimicrobial substances from its wings that counteract harmful pathogens.

Classical scholars explain that Allah has created everything with perfect balance. The fly carries harmful bacteria on one wing and the antidote on the other. This demonstrates divine wisdom in creation and teaches us that apparent evils may contain hidden benefits.

Ibn Hajar al-Asqalani comments that this hadith shows the perfection of Prophetic guidance in matters both spiritual and worldly, revealing knowledge that humans could not discover independently.

The instruction also teaches practical wisdom - rather than wasting the contaminated drink, one can purify it through this method, reflecting Islam's emphasis on avoiding waste and utilizing resources wisely.
