“Once a man informed the Sahaabee, ‘Abdullaah ibn Mas‘ood, that a group of people were sitting in the masjid after maghrib and one of them would say, “Say: Allaahu Akbar” and the rest would repeat it in unison, than he would say, “Say: Subhaanallaah”, and they would do likewise, then he would say, “Say:Al-hamdullillaah” and they would do so. Ibn Mas‘ood told the man to inform him of their whereabouts if he found them doing that again. When he went back where they were, he sat until he heard them, and he returned to inform ibn Mas‘ood. Ibn Mas‘ood went to them and said, “I am ‘Abdullaah ibn Mas‘ood. By Allaah besides who there is no God, you have wrongfully brought an innovation and considered yourselves more knowledgeable than the companions of Muhammad ( ).” ’Amr ibn ‘Utbah19 said, “I seek forgiveness Allaah!” Ibn Mas’ood said, “Adhere
closely to the Prophet’s path, for if you go to the right of it or to the left, you will go far astray.”
