The Ruling and Method of Raising the Feet During Prostration

Question:
The hadith of Aisha (may Allah be pleased with her) that she found the feet of the Prophet (peace and blessings be upon him) raised: does this not indicate bringing the feet together during prostration?

Answer:
The Sunnah is to raise them during prostration, resting on the toes.
Q: With them separated or with them together?
The Shaykh: The original practice is to separate them; because the Messenger (peace and blessings be upon him) used to separate his knees, his feet, and his hands, may Allah send blessings and peace upon him, in his prostration and his bowing. May Allah send blessings and peace upon him.
As for the narration that one heel is on top of the other: there is a concern with it, from the narration of Ibn Khuzaymah and al-Hakim. The original principle in all of this is: not bringing them together. The principle is: extending the limbs and not bringing them together. This is how the authentic Sunnah came.
Q: Is it considered anomalous?
The Shaykh: It is possible. The requirement of the rules is that it is anomalous.
