Is reciting surah fateha in funeral prayer compulsory??? plz ans me with authentic hadith thank you?

Yes, it is compulsory to read fatiha in prayer. Rasulallah (pbuh) said [no prayer to whom who don't read fatiha(the mother of the quran)].. If you need any help in it just comment. Jhazak Allah khairan for asking about you prayer and asking Allah's mercy. May Allah reward u and help u.
