Science & Hadees regarding onion: -

1. In Prophetﷺ time mostly people were poor, in Arab much vegetables did not grew, vegetables from other parts of the world were not every time available, people use to eat raw onion very often & we all know that it has a very offensive smell in breath which irritates other people, & Prophetﷺ strictly prohibited to eat, but allowed to eat it in cooked food, & prohibited to come in Masjid or near it with its smell in breath, because in Masjid there are angles, who also get irritated with its smell, And by this rule all bad smell things should be avoided in Masjid or near it. The people often use to come in Masud with its smell in breath, may be people ate raw onion in much quantity to fulfill their hunger, & it is seen that the bad smell is very offensive if raw onion is eaten in much quantity & remains for very long in the breath & also its smell is found in sweating which is again bad. And also cause excessive unwanted gas formation & its expulsion & if this occurs in public it is thing which irritates others.
2. Today no body eats onion raw enough or full stomach because today we have all types of vegetables available all season thus onion remains an ingredient of food. Thought its medicinal properties are not neglected.

If excessive raw onion is used some people may suffer from allergic reactions & also after handling onions. Symptoms can include contact dermatitis, intense itching, rhinoconjunctivitis, blurred vision, bronchial asthma, sweating and anaphylaxis. The toxicity is caused by the sulfoxides present in raw onions, causing ingestion resulting in anaemia caused by the distortion and rupture of red blood cells. (This is based on an animal’s research done by using onion.

Conclusion of Hadees: -

1. Do not come in Masjid or in public after eating raw vegetables whose bad smell comes from mouth. We can eat them cooked in food & bad smell should not come from mouth. Nabiﷺ did not liked bad smell, specially from mouth because Angle use to come to Him bringing Messages & Quranic verses from Allah & Angles get irritated by te bad smell even people get irritated.
