Mullah Ismall Mosque is the best place to get oneself freed from all the vices. As it is, any of the places of worship take one away from the seditions and prejudices. On the top of that Mullah Ismall Mosque is the only one of its kind. One just needs to come over to this place. It’s a guarantee that he/ahe would not return without having obtained solace. What else to say? One would feel closeness with God at this place. Wherever he/she happens to go, the ultimate thing which he/she desires is a sound sleep at night. There cannot be a place better than the one mentioned above; at least in Yazd. This mosque, along with Rig Mosque, makes a wonderful pair which would be entitled ‘Messengers of Peace’. The other mosques include Fort Mosque. As such, one can go to any of these three places of worship. It would be advisable to go during ‘namaz’; so that prayers cannot be missed out.
