One of the many graces which Allah (swt) has bestowed upon the generous Muslim Ummah is that He (swt) has made the whole Earth pure, so that it serves as a mosque and a grand mihrab, where Allah (swt) is worshipped in every single corner of it, whether in the mosques, in the markets, in the streets, or at schools and universities, in the houses, at the frontiers and so on.
Therefore, the whole earth is a mosque and this is indicated by the hadith reported by Bukhari and Muslim on the authority of Jabir ibn 'Abdullah that the Messenger of Allah (saw) said,'I have been granted five things which were not granted to any other prophet before me: I have gained victory with awe from the period of one month (before the battle); the Earth has been made sacred and pure and a mosque for me, so whenever the time of prayer comes for anyone of you, he should pray wherever he is; the spoils of war have been made lawful for me and these were never made lawful to anyone before; I have been granted shafa'a (intercession on the Day of Judgement); and every Prophet was sent particularly to his own people, whereas 1 have been sent to the whole of mankind."
