<b>Guidance from the Hadiths:</b><br> 1) It is prohibited to go to the mosque after eating garlic, onions, or the like of such plants that have a bad odor.<br> 2) Angels get annoyed by what annoys humans. So, a Muslim should be good-smelling, especially in places of worship and Muslim gatherings; most notable among them is prayer and learning classes.<br> Note:<br> It is permissible to eat onions and garlic. Yet, he who has eaten any of them should avoid going to the mosque to attend the congregational prayer. However, if he uses some substance that removes the bad odor, then he can go to the mosque. But it is not permissible for a person to intentionally eat onions or garlic to skip the congregational prayer in the mosque.
