Remaining Firm on the Sunnah at all Times

عن عبد الله بن عمرو رضي الله عنهما قال قال رسول الله صلى الله عليه و سلم لكل عمل شرة ولكل شرة فترة فمن كانت فترته إلى سنتي فقد اهتدى ومن كانت فترته إلى غير ذلك فقد هلك (الترغيب والترهيب 1/109)

Hadhrat Abdullah bin Amr (Radhiyallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: “For every action there is a motivation (enthusiasm in the action), and for every motivation there will be a decline. If after the decline, one’s action conforms to my sunnah (after the enthusiasm wanes, one still carries out the action in accordance to the mubaarak sunnah of Rasulullah (Sallallahu Alaihi Wasallam)), then it is a sign that one is firm on guidance, and if after the decline, the condition found is besides that (one does not carry out the action in accordance to the sunnah), then one is on the path of destruction.”
