Sayyiduna Jabir (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When any one of you performs prostration, he should do so with moderation, and he should not spread his arms like a beast."

Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Do not spread your arms like a beast, and place your palms firmly, and keep your arms away from your sides, for indeed when you do this, all the parts of your body will prostrate."

Abu Ishaq narrates that Sayyiduna Bara’ bin Azib (may Allah be pleased with him) described to us the manner of prostration. He placed both his hands on the ground and raised his buttocks upwards and said: I saw the Messenger of Allah (peace and blessings be upon him) prostrating in this manner.

It is narrated from Sayyiduna Bara’ bin Azib (may Allah be pleased with him) that he said: When the Messenger of Allah (peace and blessings be upon him) performed prayer, he would keep his stomach away from his thighs and his arms away from his sides. Sirri states that "junuh" refers to one who does not spread out during his bowing and prostration. Nadr says: The Arabs say, "He is junuh," meaning he is hunchbacked.

It is narrated from Sayyiduna Abdullah bin Malik Buhaina (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) performed prayer, he would spread his hands (so much) that his armpits would become visible.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that when the Noble Prophet (peace and blessings of Allah be upon him) performed prostration, he would keep his arms away from his sides to such an extent that the whiteness of his armpits became visible.

Hazrat Adi bin Umairah al-Hadrami narrates that when the Prophet Muhammad (peace be upon him) performed prostration, the whiteness of his armpits would be visible. In the narration of the Imam’s teacher, Muhammad bin Abdul A’la San’ani, these words are mentioned: the whiteness of his (peace be upon him) armpit would be seen.

It is narrated from Hazrat Muhammad bin Ata, who reports from Sayyiduna Abu Humayd Sa'idi (may Allah be pleased with him) that I heard him among ten companions, among whom was also Sayyiduna Abu Qatadah bin Rabi'i (may Allah be pleased with him). He says that when the Prophet Muhammad (peace and blessings be upon him) would stand for prayer, he would stand with moderation. And after narrating a part of the hadith, he said: Then the Prophet (peace and blessings be upon him) bent towards the ground for prostration, then said «‏‏‏‏اللهُ أَكْبَرُ» ‏‏‏‏, then kept both his arms away from his sides and spread the toes of his feet.

Hazrat Muhammad bin Amr bin Ata narrates that he was sitting with a group of the noble Companions when they discussed the prayer of the Messenger of Allah, peace and blessings be upon him. Then Sayyiduna Abu Humaid Sa’idi, may Allah be pleased with him, said: I remember the prayer of the Messenger of Allah, peace and blessings be upon him, better than all of you. (I saw the Messenger of Allah, peace and blessings be upon him, that when he said «‏‏‏‏اللهُ أَكْبَرُ» ‏‏‏‏ to begin the prayer, he raised both his hands up to the level of his shoulders. Then when he bowed for ruku’, he firmly placed both his hands on his knees. Then he bent his back. Then when he raised his blessed head, he stood up completely straight until every bone of his returned to its place. And when he performed sajdah, he neither spread his hands too wide nor kept them completely close, and he directed the toes of both his feet towards the qiblah.)

Abu Hurairah (may Allah be pleased with him) narrates from the Messenger of Allah (peace be upon him) that he (peace be upon him) said: "When any one of you performs prostration, he should not spread his hands the way a dog spreads them, and he should bring his thighs together."
