Prostration is an important and essential part of the prayer, and is a way in which a person shows submission and humility to his Lord. Allah (may He be exalted) enjoined it in several places in His holy Book. In this hadith, the Prophet (blessings and peace of Allah be upon him) explains the correct way to prostrate. He tells us that Allah (may He be glorified and exalted) commanded him to prostrate on seven “bones”, meaning bones of the body. These seven parts are the forehead, which is the part of the face above the nose and eyes, and the Prophet (blessings and peace of Allah be upon him) pointed to his nose, explaining that the forehead and nose together form one of these seven, and confirming that the one who prostrates should make his nose touch the ground. [These seven] also include the two hands, the two knees and the toes of the two feet and what is next to them. The two hands, the two knees and the two feet are the other six parts. And we should not tie up our garments or hair. Tying up the garment means tucking it up so that it will not drop or hang down. Tying up the hair means tying it with something so that it will not drop down and fall loose. What is meant is that we should not tuck up our hair or garments when prostrating on the ground in order to protect them; rather we should leave them as they are, so that they will fall on the ground and prostrate with the other parts of the body. The wisdom behind that is that if a person lifts up his garment and hair, and prevents them from touching the ground, he will be like one who is arrogant. It was also said that the hair will prostrate with the head if it is not tied up or wrapped up..
