The prayer of the sick and the prayer of one sitting

Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) went to visit a sick person, and I was with him. The Prophet (peace and blessings be upon him) saw that the man was praying and prostrating on a pillow, so the Prophet (peace and blessings be upon him) forbade him. He said: "If you are able to prostrate on the ground, then prostrate; otherwise, make gestures, and (while gesturing) bend lower in prostration than in bowing."
Al-Bazzar recorded it, and Abu Ya'la recorded something similar, except that he narrated these words: "The Prophet (peace and blessings be upon him) went to visit a sick person. He saw him praying on a pillow (that is, prostrating on a pillow), so he put the pillow aside. The man then took hold of a piece of wood and was praying with its support, so he put that aside as well." The narrators of al-Bazzar are the narrators of the Sahih.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) went to visit a sick man from among his Companions, and I was with him. When the Prophet (peace and blessings be upon him) reached that man, he was praying with the support of a piece of wood, placing his forehead on the wood. The Prophet (peace and blessings be upon him) gestured to him, so he put the wood aside; then he took a pillow. The Prophet (peace and blessings be upon him) said to him: "Leave it. If you are able to prostrate on the ground, that is fine; otherwise, make gestures, and bend lower in prostration than in bowing."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Hafs bin Sulayman al-Minqari, who is matruk (abandoned). Different reports are transmitted from Imam Ahmad about his trustworthiness; the correct report is that he declared him da'if (weak), and Allah knows best. Ibn Hibban mentioned him in the book al-Thiqat.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Whoever among you is able to prostrate should prostrate; and whoever is not able to, should not raise anything up to his forehead in order to prostrate on it. Rather, he should perform his bowing and prostration by gesturing."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "The sick person should pray standing. If he experiences hardship, he should pray sitting. If he still experiences hardship, he should pray lying down, gesturing with his head. If he experiences hardship even in that, then he should recite tasbih (glorification)."
Al-Tabarani recorded it in al-Mu'jam al-Awsat and says: No one narrated it from Ibn Jurayj except Hils bin Muhammad al-Dab'i. (Allamah al-Haythami says:) I say: I have not found anyone who has given his biography. The remaining narrators of this narration are thiqat (trustworthy).

It is reported about Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he visited his brother Utbah, who was praying with the support of a miswak which he would raise to his face. Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) took the miswak from him and put it aside, and then said: "Pray by gesturing, and in your bowing remain a little higher than in your prostration (that is, do not lower the forehead as much)."
Al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy).

Ibrahim al-Nakha'i says: Alqamah and al-Aswad came to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). They both said: "The mother of al-Aswad has been made to sit, and a piece of wood is placed for her on which she prostrates. What is your view about this?" Sayyiduna Abdullah (may Allah be pleased with him) said: "I consider that Shaytan is behind this piece of wood. The woman should prostrate on the ground if she is able to; otherwise she should prostrate by gesturing."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; Ibrahim al-Nakha'i did not meet the time of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), and the rest of its narrators are thiqat (trustworthy).

Mukhtar says: I asked Sayyiduna Anas (may Allah be pleased with him) about the prayer of a sick person, and he said: He should perform the bowing and the prostrations while sitting in the obligatory prayer.
