What is called the "Rajab visit" to the Prophet's Mosque.

The Shaykh : Fourth: Visiting the Prophet's Mosque. Some people believe that visiting the Prophet's Mosque in Rajab has a special merit, and they come to it from every direction, calling this visit the "Rajab visit." This is also a religious innovation (bid'ah) with no basis. The predecessors did not speak of it, nor did those after the first three generations, because it appears that it occurred very late. Therefore, it is an innovation. However, if one visits Madinah in Rajab, not because it is the month of Rajab, there is no blame on him. But if one believes that visiting the Prophet's Mosque in Rajab has a special merit, he has erred and gone astray, and he is among the people of innovation in this matter.
Fifth: Many people believe that the Ascension (al-Mi'raj) of the Messenger of Allah (peace and blessings be upon him and his family) to the heavens took place in Rajab, on the twenty-seventh night of it. This is a mistake.
