Masjid Nabawi @night.
Makam Para Syuhada (close up).
Beside asjidil nabawi is a huge piece of land (about 6-8 times bigger than dataran merdeka), called al-baqi. this is where more than 10,000 syuhadas, nabi's companions and many other great names in islam were buried. to date, al-baqi continues to be used as a burial ground and could see burials made every day (as common as solat jenazah after every solat fardu) there.
There are no tombstones, but only simple stones the size of a football as a mark. when the land is full, the bodies will be dug out and buried in one liang lahad, thus the rest of the space can be used again. in this pic, you can see there were two groups bringing jenazah for burial.
