Google Earth proves that the Prophet Muhammad (peace be upon him) is right

No human on earth can draw a straight line on the surface of the earth between two far cities except with the aid of detailed maps, made possible today due to airplanes, satellites, and knowledge of latitude, longitude, and land height. However, there was a person who had done this 1400 years ago. This person is the prophet Muhammad (peace be upon him).

While the prophet Muhammad (peace be upon him) was in Madinah Al-Munawarah, Allah instructed him that he should face in the direction of the Sacred Mosque in Makkah. From then on, it became the Qiblah for Muslims. And from then on, Islam was spreading. After the victory of (Fatih Makkah) people came and entered Islam. Then, the prophet (peace be upon him) started to sent the teachers to these people to teach them Islam. One of them Wabr ibn Yohanas Al-Khozaee whom the prophet (peace be upon him) sent to Yemen (Sana’a). He was ordered to teach people of Sana and to build them a Mosque by features the prophet (peace be upon him) had defined to him.

Al-Tabarani narrates in the Mu’jam Al-wsat saying:

Wabr ibn Yohanas Al-Khozaee said: the prophet (peace be upon him) said to me ‘ if you build the mosque of Sana’a, make it to the right of a mountain called Deyn’
To explain, Al-Hafez Al-Rahzey says in his book ‘The History of Sana’a) that the prophet (peace be upon him) ordered Wabr ibn Yohanas Al-Khozaee to build the mosque in Bathan park, from where is found a rock in Gamdan and face it to a mountain called Deyn

The prophet Muhammad (peace be upon him),1400 years age, ordered to build the mosque Sana’a facing Jabal-e-deen .If we use Google Earth and draw a straight line from the mosque Sana’a to the Qibla which is in Makkah, it will pass through the peak of jabal-e-deen and will end at the center of Kaba.

How could someone 1400 years ago have shown the exact direction for kaba from a far away city without using the new aids needed for such a process
