I can't say until now I've ever had the displeasure of praying beside someone who reeked of garlic. And now I know good and well why someone who has been eating raw garlic isn't supposed to go pray at the masjid! That's a hadith you can find easily in Sahihs Bukhari and Muslim. I did find one hadith where a Companion had gone to pray behind the Prophet (s) and smelled of garlic and the Prophet (s) told him, but upon discovering that the man had a "belt" tight around his chest, he said the man had an excuse.
I wasn't sure what the meaning of this "belt" was. It could be that the garlic was part of an ointment on an injury or something to that effect.
I only bring it up, because I happen to know someone who frequently eats raw garlic (apparently for the health benefits) and then goes to pray in the masjid. It bothered me this morning when I went to pray fajr... the sister beside me and I were praying peacefully... until she bumps into me and I realize that there is a third person in our row now and I move slightly so we can each have a share on the two rugs laid down, and then I smell it.
I kind of wonder, now, if not using garlic to treat a problem but just using it as a generic and regular dietary supplement (yes... eating whole cloves...) implies that the person is excused? Or if she (or in other cases he?) should be aware that this odor is not pleasant to the other worshipers during their salaat.
Should I mention this to her? That I could smell her though there was a person between us? Ask the imam about it? I know this sister know these ahadith about garlic, so it's just odd to me that she chooses to disregard them. I would like to suggest that she not try to pray in a row of sisters if she's been eating garlic but on the other hand, I'm not sure if there's a nice way to make that suggestion...
And you know, a few days ago I bought my first garlic press, hoping to start using fresh garlic (instead of dried minced garlic in a spice jar) in some dishes I want to try. I'm going to have to be wary of when I use garlic to cook and make sure it's cooked. I tried getting some for bread the other day and the kitchen smelled for about two days after.
