A woman, like a man, may offer a funeral prayer, singly or in a congregation. In fact, once when Umm ‘Abdallah offered funeral prayer for ‘Utbah, ‘Umar waited until she finished. ‘Aishah ordered the body of Sa’d ibn Abi Waqqas to be brought to her so that she could offer a funeral prayer over him.
An-Nawawi said: “Women may offer (funeral) prayer in congregation just as they are permitted to perform other sunnah prayers. Al-Hasan ibn Saleh, Sufiyan Al-Thawri, Ahmad, and the Hanafi school also hold the same view. Malik, however, is of the opinion that women should offer the funeral prayer individually.
