Righteous deeds in Makkah are better than those done elsewhere, but we do not know to what degree they are better, except in the case of prayer
Question

                “Fasting Ramadan in Makkah is equivalent to fasting one thousand months elsewhere.” Is this a saheeh hadith?
Praise be to Allah.
	It is not saheeh; 
	it is a da‘eef (weak) hadith that is not soundly narrated. Rather what is 
	proven mentions the prayer only; one prayer in al-Masjid al-Haraam is 
	equivalent to one hundred thousand prayers offered elsewhere, and one prayer 
	in the Mosque of the Prophet (blessings and peace of Allah be upon him) is 
	better than a thousand prayers offered elsewhere. As for fasting, there is 
	no proven report about it, except for a da‘eef hadith which says that it 
	[fasting Ramadan in Makkah] is better than one hundred thousand elsewhere. 
	But it is da‘eef (weak). However, righteous deeds have a special virtue when 
	done in Makkah; fasting, giving charity, reciting adhkaar and other 
	righteous deeds have a special virtue. But there is no evidence to prove the 
	degree to which they are better (than righteous deeds done elsewhere), apart 
	from prayer. End quote.
