What is the ruling on one who prostrates on the fingers of his hands and does not place his palms fully on the ground?

Question:
Some of the people who pray, when they prostrate, prostrate on the fingers of their hands and do not place their palms fully on the ground. What is the ruling on that?

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. As for what follows, the Prophet (peace and blessings be upon him) said: The face, the palms, the knees, and the toes of the feet, the tips of the feet. These are the limbs of prostration, so it is necessary to place them on the place of prayer, either directly on the ground if one is praying on the ground, or on the prayer mat one is praying on, such as a carpet or the like. It is not permissible for him to raise any of these limbs completely. If he raises a limb completely in all the prostrations, and does not place it down without a valid religious excuse, his prostration is not valid. If he raises part of it, his prostration is valid, but there is a deficiency in it. So this person who places the tips of the fingers of his hands and raises his palms from the ground, and most of his palms, this has a great deficiency in it, but it is not said that his prayer is invalid; because he placed part of the limb on the ground. Yes.
