This verse speaks of the few people on earth, the "strangers", who prohibit mankind from evil. These are the same people the Prophet (peace be upon him) spoke about when he said, "Islam began as something strange, and it shall return to being something strange, so give glad tidings [ar. Tooba. This is a tree in Paradise. So the Prophet (peace be upon him) is giving the good news of Paradise to these strangers.] to the strangers." It was asked, "Who are those strangers, O Messenger of Allah?" He replied, "Those that correct the people when they become corrupt." [Reported by Abu Amr al-Dani, from the hadith of ibn Masoud. It is authentic according to al-Albani. Another narration says, "Those that correct my sunnah which has been corrupted by the people after me."] In another narration he said in response to the same question, "They are a small group of people among a large evil population. Those who oppose them are more than those who follow them." [Reported by ibn Asaakir. It is authentic according to al-Albani.]
