This Hadith tells us that Salat in congregation is far more in reward than Salat offered alone. In the preceding Hadith it has been held 27 times and in the present, 25 times more rewarding. The reason for this variation offered by some 'Ulama' is that at first it was told to the Prophet (PBUH) 25 times and then it was increased to 27 and he communicated to his Companions what was revealed to him. Some other scholars have linked it with the form, spirit and concentration of the Salat. The more meticulous one is about its details, the greater will be the reward for it. Another difference of opinion in this respect is regarding the nature of Salat in congregation. How does one become eligible for higher reward? Does he become eligible for it by performing Salat in congregation anywhere, i.e., at home, in business premises, at an open place, in the desert etc., or in that congregation which gathers in a mosque? Some 'Ulama' go with the first opinion while others agree with the second. Hafiz Ibn Hajar preferred the second view on the grounds that the words occuring in the text of this Hadith support this view.
