If it were difficult for a person

The Shaykh : However, if a person is heavy or ill, or has something in his knees that makes prostrating on them difficult, then in this case we say there is nothing wrong with a person doing so and placing his hands forward. The prohibition applies only as long as there is no cause necessitating it. If a cause necessitating it exists, such as the need due to illness, old age, pain in the knees, or otherwise, then there is nothing wrong with it. This is because the Islamic religion, praise be to Allah, is based on ease and simplicity. In the Noble Qur'an, Allah the Exalted says: The intention here is legal, meaning that the Shari'ah is the one that facilitates.
And in the Sunnah, [the Prophet] was sent with the smooth, easygoing Hanifiyyah: ease and no hardship. So the objective is to reach prostration. If a person is able to do it in the most perfect manner, that is better. If it is difficult for him, then he does what is easy for him.
