Excellence of offering Salaat in Masjid Nabawi
Masjid Nabawi is that great Masjid which is identified with the Holy Prophet (Sallallahu alaihi wa sallam). He (Sallallahu alaihi wa sallam) stayed there, His house was here and His blessed grave is also here.
There is a Hadith in Sahih Bukhari:
Translation: It has been narrated on the authority of Hadhrat Abu Hurairah (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: Offering 1 Salaat in my Masjid is better than offering 1000 Salaat in any other Masjid except Masjid Haraam. (Sahih Bukhari, Hadith No. 1190)
Offering 1 Salaat in Masjid Nabawi fetches reward of 50000 Salaat. There is a Hadith in Sunan Ibn Majah:
Translation: Offering 1 Salaat in my Masjid has the reward of offering 50000 Salaat. (Sunan Ibn Majah, Hadith No. 1478)
