Book Name:Masjid Ke Adaab
7. Whenever you go from one part of the masjid to the other (for instance, going to the courtyard of the masjid or going from the courtyard to the inner portion), place your right foot first.

Try your best to keep your mouth closed when yawning, because if a person yawns with the mouth open, the devil spits in it. If the yawn does not stop, press your lower lip with your upper teeth. If this does not help, avoid opening your mouth too much and put the back of your left hand over the mouth. As yawning is from the devil and the prophets عَـلَـيْهِمُ السَّلَام are safe from it, if you begin to yawn, recall that the
