Are there manners for clipping nails, and is it true to start with the right index finger then the rest of the fingers, and is there any evidence for that?

The Hanbalis recommended trimming nails starting with the right pinky, then the middle finger, then the thumb, then the ring finger, then the index finger. After that, the left thumb, then the middle finger, then the pinky, then the index finger, then the ring finger. In contrast, the Shafi'is hold that one should start with the right index finger due to its nobility, then the middle finger, then the pinky, then the ring finger, then the thumb. Then, the left pinky, then its ring finger, then the middle finger, then the index finger, then the thumb. After that, the right foot's pinky to the left foot's pinky. Ibn Daqiq al-Id, however, holds that there is no legal basis for the popular specific method of trimming nails, and استحباب (recommendation) is a legal ruling that requires evidence. This negation does not include starting with the right side when trimming, due to the generality of Aisha's — may Allah be pleased with her — saying: "The Prophet, peace and blessings be upon him, loved to start with the right side in putting on his sandals, combing his hair, purifying himself, and in all his affairs."
