I have managed to get this map on by further reducing the quality/size of map. The numbers highlighted are the street numbers and are written parallel to the street they belong to. You will see in Mina on the sign boards you will have street no. and street name on the sign boards (so numbers will do the job as I didn't want to put too much with my messy hand writting on the map ).
Where letter 'H' has been put in, this indicates the presence of some sort of medical facility. Although I am not sure what kind of facility it is i.e. a hospital or just a small clinic etc.
Rest from Muzdalifah and Haram it is relatively easy to get to Mina as the pedestrian routes are all well signed. Its the valley of tents where everything is similar and most of the time during Hajj is spent that we struggle.
Hope this will help Insha Allah while you are their. Don't forget me in your duas and I might bump into one of you there. May Allah accept our intentions for Hajj and accept our Hajj and reward us with Jannah. Ameen.
