'He never yawned once, for indeed yawning is from Satan.' *Many make the mistake of seeking refuge with Allah from Satan when yawning… this is something the Prophet () has not obligated upon the Ummah.
Manners that Relate to Belching/Burping *Belching is to expel gas noisily from the stomach through the mouth on account of one being full. It is usually accompanied with a foul odor. The Prophet () said:
'Relieve us from your belching, for the people who are most full in this life, will stay hungry for the longest period of time in the Hereafter.'
It is unpraiseworthy for one to belch in the presence of others.
*Some doctors mention that the cure for belching is that one eat or drink Za'tar (thyme) or mint.
*There is no certain statement one should say to the one who belches. Ibn al-Muflih, may Allah have mercy on him, said: 'The one who belches is not to be answered with anything in particular, Ibn Aqeel and others said that it was praiseworthy for one to make du'aa for the one who belches if he says 'Alhamdulilah'. He said: 'There is no authentic Sunnah in this matter; rather, this is a falsified account.'
