It is narrated from Sayyiduna Wa'il bin Hujr (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) performed prostration, he would place his knees on the ground before his hands. In the narration of Ahmad and Raja, these words are mentioned: I saw the Prophet (peace and blessings be upon him) that when he performed prostration, he placed his knees before his hands.

At the time of lowering oneself to prostration, it is abrogated. Some of those among the people of knowledge who did not understand that it is abrogated erred in using it as evidence, so they considered acting upon the report and beginning by placing the hands on the ground before the knees.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he used to place his hands on the ground before his knees and used to say that the Messenger of Allah (peace and blessings be upon him) did likewise.

When the instruction to place the hands before the knees was given earlier, and the instruction to place the knees before the hands was given later, then the earlier is abrogated, and the later is the abrogator.

Sayyiduna Sa’d (may Allah be pleased with him) narrates that we used to place both hands (on the ground) before the knees, then we were commanded to place both knees before both hands.

It is narrated from Sayyiduna Wa'il bin Hujr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him), (when performing prostration), would place his knees on the ground before his hands, and when rising (from prostration), he would lift his hands before his knees.

Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates a marfu’ hadith that indeed both hands prostrate just as the face prostrates. Therefore, when any one of you places his face (on the ground), he should also place both his hands, and when he raises his face, he should also raise both of them.

It is narrated from Sayyiduna Abbas bin Abdul Muttalib (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings be upon him) saying, "When a servant prostrates, seven parts of his body also prostrate with him: his face, his two hands, his two knees, and his two feet."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "I have been commanded to prostrate on seven body parts, and (I have been commanded) not to gather my hair and clothes."

Sayyiduna Ibn Abbas (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "I have been commanded to prostrate on seven bones, and not to gather (lift up) my hair and clothes."
