‘Abdur-Rahmaan al-Awzaa’ee 157 AH (May Allah have mercy on him) said:

اصبر نفسك على السنة و قف حيث وقف القوم و قل بما قالوا

و كف عما كفوا عنه, واسلك سبيل سلفك الصالح. فانه يسعك ما وسعهم

“Have patience upon the Sunnah, and stop where the people stopped (the Companions may Allah be pleased with them all) and speak with what they spoke with and hold back from what they held back and travel upon the path of the Salafu’s-Salih, for verily, what sufficed them will suffice you.”
