Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: Sayyiduna Abu Bakr (may Allah be pleased with him) wrote a letter to Sayyiduna Amr bin al-As (may Allah be pleased with him) saying that the Prophet (peace and blessings be upon him) used to seek counsel regarding war, so it is incumbent upon you to adopt it.
Al-Tabarani recorded it, and its narrators have been declared trustworthy.
