Hadith.686 - The Messenger of Allah صلى الله عليه وعلى آله وسلم said:
"Whoever comes to my mosque, the Mosque of Quba, and prays two rak'ahs in it, it is as if they have performed an ‘Umrah."
He عليه السلام would go there and pray in it with adhan (call to prayer) and iqamah (call to commence prayer).
It is recommended to visit the mosques in Madinah, particularly the Mosque of Quba, for it is the mosque founded upon piety from the first day. Also recommended are Mashrabat Umm Ibrahim, the Mosque of al-Fadikh, the graves of the martyrs at Uhud, and the Mosque of al-Ahzab (the Mosque of Victory).
Additionally, it is recommended to pray in the Mosque of Ghadir on the left side, for it is the place where the Messenger of Allah صلى الله عليه وعلى آله وسلم stood when He said: 'Whomsoever I am his master (mawla), Ali is his master. O’ Allah سبحانه وتعالى, befriend those who befriend him, and be hostile to those who are hostile to him.'"
