"I used to recite Qur'an to my father on the road, and if I recited a verse in which prostration was required, he would prostrate. I said: 'O my father, do you prostrate on the street?' He said: 'I heard Abu Dharr say: "I asked the Messenger of Allah (ﷺ): 'Which Masjid was built first?' He said: 'Al-Masjid Al-Haram.' [1] I said: 'Then which?' He said: 'Al-Masjid Al-Aqsa.' [2] I said: 'How long was there between them?' He said: 'Forty years. And the earth is a Masjid (or a place of prostration) for you, so wherever you are when the time for prayer comes, pray.'" [1] In Makkah. [2] "Furthest Masjid", meaning the Masjid in Jerulsalem.

"Whoever prays in the Masjid of the Messenger of Allah (ﷺ) (that is good), for I heard the Messenger of Allah (ﷺ) say: ' One prayer offered there is better than a thousand prayers offered elsewhere, except the Masjid of the Ka'bah.'"
