وعن العرباض بن سارية رضي الله عنه
قال: وعظنا رسول الله موعظة وجلت منها القلوب، وذرفت منها العيون وذكر الحديث وقد سبق بكماله في باب الأمر بالمحافظة على السنة، وذكرنا أن الترمذي قال: (إنه حديث حسن صحيح)
One day, Messenger of Allah (sallallahu alayhi wa sallam) delivered a very effective speech, as a result, eyes shed tears and hearts became softened. A man said: “O Prophet of Allah! It sounds as if this is a farewell speech, so advise us.”
He (sallallahu alayhi wa sallam) said, “I admonish you to fear Allah, and to listen and obey even if a black slave has been appointed as your leader. For whoever among you lives after me will see much discord. So hold fast to my Sunnah and the Sunnah of the Rightly-Guided Caliphs who will come after me. Adhere to them and hold fast to them. Beware of Bidah (in religion) because every Bidah is a misguidance.”.
