My friend passed away a couple of weeks ago and by the time I got to the masjid they had already finished the janazah prayer. 1) Can I go to her grave and pray the janazah prayer? 2) Can I pray it anywhere else other than at her grave? 3) Can someone who has already prayed it pray it again?
There's no harm inshaAllah to go to her grave, even if you're a group of women, and pray Janaza, even if some of you have prayed her Janaza before.
Yes to all 3 questions.
