1.         onto the floor of the Masjid with your right foot (i.e. whilst walking, step onto every mat with your right foot first). Likewise, when the Khateeb (religious orator) steps onto the Mimber (the pulpit) he should place his right foot on it first and he should also step off the Mimber with his right foot first.

2.         If you sneeze or cough in the Masjid, try to keep the voice as low as possible. The Beloved and Blessed Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم disliked the loud voice of sneezes in the Masjid. One should also avoid belching. If it is not possible to stop a belch, one should keep the sound as low as possible whether he is in the Masjid or not. Care should also be taken in this regard whilst one is present in an Ijtima’/gathering or before a religious personality.

A blessed Hadees states, ‘A man belched in the presence of the Holy Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. He صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, ‘Keep your belch away from us as those who fill their stomachs in the world will remain hungry for a long time in the Hereafter.’ (Sharh-us-Sunnah, vol. 7, pp. 293, Hadees 3944)

One should not make a sound whilst yawning, whether he is in the Masjid or anywhere else because yawning is the laughing of the devil. Try your best to keep your mouth closed (because) when a person yawns the devil spits into his mouth. 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 Prophets عَـلَيْهِمُ السَّلَام are safe from it, so if you begin to yawn, recall that the Prophets عَـلَيْهِمُ السَّلَام never yawned, this thought will instantly supress the yawn, اِنْ شَــآءَالـلّٰـه عَزَّوَجَلَّ.

(Rad-dul-Muhtar, vol. 2, pp. 498-499)

3.         Joking is already forbidden and is strictly impermissible in the Masjid.

4.         Breaking wind in the Masjid is prohibited.

5.         Stretching your legs towards the Qiblah is prohibited everywhere and one should avoid doing so towards any direction in a Masjid as it is quite inappropriate at such an honourable place.
