There are hadith on the merits of fasting and praying on 27th Rajab. Although they are weak, because they are on merits, they are accepted and acted upon.
Sunni ulama of Syria, Yemen, Madinah, Morocco and Egypt perform these practices. And, of course, Sunnis of the subcontinent certainly do so.
There is ijma'a of scholars that weak hadith are allowed to be acted upon in the chapter of merits.
#Alahazrat cites various references beginning at 10:647 in his fatāwā.
