Those who disliked interlacing the fingers in prayer in the mosque

A freed slave of Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said that he was with Sayyiduna Abu Sa'id al-Khudri while he (Abu Sa'id) was sitting with the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) entered the mosque and saw a man sitting in the middle of the mosque with his fingers interlaced, talking to himself. He gestured to him to stop, but the man did not understand. Then he (peace and blessings be upon him) turned to Sayyiduna Abu Sa'id al-Khudri and said: "When one of you prays, he must not interlace his fingers, for interlacing the fingers is from Satan. And you remain in prayer as long as you are in the mosque."

Sa'id bin al-Musayyib said: The Prophet (peace and blessings be upon him) said: "When one of you is in the mosque, he must not interlace his fingers."

Abu Thumamah al-Qammah said: I met Sayyiduna Ka'b (may Allah be pleased with him) at al-Balat, and I had interlaced my fingers. He struck my hand hard and said: We were forbidden from interlacing our fingers in prayer. I said to him: May Allah Almighty have mercy on you, do you see me in prayer? He said: Whoever performs ablution and then sets out for the mosque is in prayer.

Al-Nu'man bin Abi Ayyash said: The predecessors used to forbid interlacing the fingers in prayer.

Ibrahim considered it disliked (makruh) to interlace one's fingers in prayer.
