It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the saying of Allah Almighty: "O you who believe, obey Allah and obey the Messenger and those in authority among you" [al-Nisa: 59] was revealed concerning Sayyiduna Abdullah bin Qays bin Adi (may Allah be pleased with him), whom the Prophet (peace and blessings be upon him) sent as the commander of a military detachment. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
