Wa alaykum salam wa rahmatuLlahi wa barakatuHu,

If a Friday prayer and funeral prayer enter, and time is not tight, then the funeral prayer must be made first. If time is tight, then the Friday prayer may be performed first. (Sharh al-Muhadhdhab v. 5, p. 56; Tuhfat al-Muhtaj v. 3, p. 64)

Ibn ‘Abd al-Salam was in charge of the Friday prayer in Egypt’s ‘Amr b. al-As mosque. He would perform the funeral prayer before the Friday prayer, and then give fatwa that those needed to carry the deceased and the deceased’s family should proceed for burial (without performing the Friday prayer first). (Tuhfat al-Muhtaj v. 3, p. 64)

And Allah knows best.
