Does traveling to visit the mosque of Sidi Abul Hasan al-Shadhili contradict the saying of the Prophet, peace and blessings be upon him: "Journeys are not undertaken except to three mosques: this mosque of mine, al-Masjid al-Haram, and al-Masjid al-Aqsa"?

It is not permissible to travel to Al-Shadhili Mosque or any other mosques of the Muslims with the intention of worship, prayer, and i'tikaf, with the exception of the three mosques: Al-Masjid Al-Haram (The Sacred Mosque), Al-Masjid An-Nabawi (The Prophet's Mosque), and Al-Masjid Al-Aqsa (The Farthest Mosque). This is based on the saying of the Prophet, peace and blessings be upon him: "Journeys are not undertaken except to three mosques: Al-Masjid Al-Haram, this mosque of mine [the Prophet's Mosque], and Al-Masjid Al-Aqsa."
