What is the authenticity of the Hadith: "Be inclined to the right whenever you can," and what is its type? Is it acted upon? And did the Messenger always choose the easier of two matters when given a choice?

The Hadith (definition) "Perform acts of Tiyāmun (starting with the right) as much as you can" with this exact wording has not been found. However, it was reported by Aisha that the Prophet (peace and blessings be upon him) loved to start with the right in all his affairs, such as purification, combing his hair, and putting on his sandals, and this is an authentic Hadith. A Muslim must emulate the Prophet (peace and blessings be upon him) and act upon what has been authentically reported from him, unless something contradicts or abrogates it. Therefore, one should act upon these two Hadiths.
