There are four Takbir's in the funeral prayers

وَقَالَ حُمَيْدٌ صَلَّى بِنَا أَنَسٌ رَضِيَ اللَّهُ عَنْهُ فَكَبَّرَ ثَلاَثًا ثُمَّ سَلَّمَ، فَقِيلَ لَهُ فَاسْتَقْبَلَ الْقِبْلَةَ، ثُمَّ كَبَّرَ الرَّابِعَةَ ثُمَّ سَلَّمَ.Humaid said: “Anas led a funeral prayer and said three Takbir and then performed Taslim. When he was told about it he faced the Qiblah and said the fourth Takbir and performed Taslim (again).”
