Shia scholar Muhammad Shirazi in his book “al-Baqiyah al-Garqad” (p 26) said:

Translation:

Even their scholar(bin Baz) doesn’t visit mosque of messenger (sallalahu alaihi wa ali), and saying: As long as that Idol (Qubbah of Prophet) is there, I wouldn’t visit it..

There is no doubt that this is lie of shia scholar upon scholar of Islam, shaykh Bin Baz (rahimahullah).

Shaykh Bin Baz said:

Going to Madinah at any time with the intention of visiting the Prophet’s Mosque is a sunnah, as is performing salah in it, According to a hadith of the Prophet (may peace and blessing of Allah be on him), a salah performed in the Prophet’s Mosque is better than a thousand salats in any other place excepting the Sacred Mosque (Masjid al-Haram) in Makkah.

See: A Guide to Hajj, Umrah and Visiting the Prophet Mosque , chapter – Visitation Of The Prophets Mosque

Salam alaikum.

I was browsing site of grand ayatolla al-Shirazi.  Translator of his answers, added some info from himself in the text. He said:

Translator’s note:

Some of the Sunni sources, which report this event, are as follows:

1. Ibn Hajar al-‘Asqalani, Lisaan al-Meezaan, vol. 1, p 268
2. Muhib-id-Deen al-Tabari, Thakha‘er al-‘Uqba, vol. 6, p17
3. Al-Shahrestaani, al-Melal wa al-Nahal, vol. 1, p 57
4. Al-Mas’udi, Ithbaat al-Waseyyah, p 142

Praise to Allah! Masudi wasn’t sunni. But he was shia, as we have mentioned before.

History of al-Ya`qûbî and Muruj az-zahab of Masoode, Both of them were shias
