Al-Madinah is a sacred city, as Ali Ibn Abi Taleb (may Allah be pleased with him) narrated that The prophet had said :
(AL-Madina is a sanctuary from that place to that. Its trees should not be cut and no heresy should be innovated nor any sin should be committed in it, and whoever innovates in it an heresy or commits sins (bad deeds), then he will incur the curse of Allah, the angels, and all the people).
Demarcation marks appear notably at the boundaries of the city. This sacred cordon though requires no special religious garb (Ehram), but it should be observed in such way no tree shall be cut, no brute should be hunted. It is a declared safe peaceful area for all creatures. Respecting it is abidance to the orders of God Almighty and respecting his Prophet (peace be upon him) as well.
It is considered as the second of the two holy mosques, and one of the three mosques that Muslims might set a journey to visit, as been quoted from the Prophet (peace be upon him). : (Narrated Aba Huraira the Prophet (peace be upon him) said (do not set out) any journey except for three mosques i_e Al-masjid al_haram(at Makka), masjid ar-Rasul (the mosque of Allah’s messenger at al-madina) and masjid al-aqsa (al-aqsa) mosque of jerusalem). No wonder the mosque has its special respect in the consciousness of every Muslim. Upon building The prophet participated in the erection process, using his own honorable hands, making it his government headquarter, and so did his companions after him. As from that date the mosque is still playing its great role sending the faith messages round the world. It is a place of worshiping God, a school to gain knowledge and a base calls to Islam.
At the east-south there is the holy chamber known as the house of the Prophet (peace be upon him), where he used to live with his spouse (Aisha) mother of the believers and when died he had been buried in it directed towards the (Quiblah). Then his companion Abu Baker was buried one yard backward. Prophet’s chamber has a door opens towards the Holy hall which placed between the prophet’s home and the holy niche (Mihrab). In this context it has been narrated that The prophet had said (between my house and my pulpit there is a garden from amongst of the Paradise)
The hall area is about (330) square meters. At the center of western side there is the tribute of the prophet (peace be upon him) and the holy hall is in the west. The stone pillars are scattered and decorated with golden lines to recognize it from among the other pillars of the mosque.
Some of them bear writings refer to specific historical events. For instance some bear names such like (A- toba) ‘(Al-wotoa)’ (Al-sareer), (Al-mukhalaka) and (Aisha) (may Allah be pleased with her). One of the holy mosque land marks is (Al-sifa) which is the place located in the rear area of the holy mosque, prepared as residence for bachelors poors and visitors who have no place to stay at. The main traits of this place is the huge domes, minarets, passages, halls and canopies.
