Leading Janazah Prayer for one's brother

A 2: First, it is permissible for you to lead the Janazah Prayer of your deceased brother, even if other more qualified people to lead the Prayer are there, except if your brother had left a will requesting that another person lead it. Second, repeating the same Janazah Prayer by the person who offered it is impermissible, but if a person offers it and then enters another Masjid (mosque) or cemetery and finds a Janazah Prayer for the same deceased, they may pray it again to win more Thawab (reward from Allah) for themselves and for the deceased. However, if a person did not attend the Prayer, it is Mustahab (desirable) for them to offer it for the deceased, even if in the cemetery, whether before or after the burial. This ruling is supported by the Hadith related on the authority of Abu Hurayrah (may Allah be pleased with him) that A black woman who used to care for the Masjid died, and people offered Janazah Prayer for her at night. However, the Prophet (peace be upon him) did not hear the news of her death, and later when he was informed of it he said: ''Why did you not inform me of her death!'' (It seemed as if people [Abu Hurayrah says] had underestimated the matter). (Part No. 7; Page No. 281) Hence, the Prophet (peace be upon him) asked them about the place of her grave, and offered Janazah Prayer for her. (Agreed upon by Al-Bukhari and Muslim)May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
