Yahya related to me from Malik from Abdullah ibn Dinar that he had seen Abdullah ibn Umar with a man praying at his side. When the man sat in the fourth raka, heput both feet to one side and crossed them. When Abdullah finished, he disapproved of that to him, and the man protested, "But you do the same." Abdullah ibn Umar said, "I am ill."
Muwatta Malik Book 3, Hadith 52
← Previous Hadith Yahya related to me from Malik from Muslim ibn Abi Maryam that AIi ibn Abd ar-Rahman al-Muawi said, "Abdullah ibn Umar saw me playing with some small pebbles in the prayer. When I finished he forbade me, saying, 'Do as the Messenger of Allah, may Allah bless him and grant him peace, did.' I said, 'What did the Messenger of Allah, may Allah bless him and grant him peace, do?' He said, 'When he sat in the prayer, he placed his right hand on his right thigh and he closed his fist and pointed his index finger, and he placed his left hand on his left thigh. That is what he used to do.' "

Muwatta Malik Book 3, Hadith 51 Next Hadith → Yahya related to me from Malik from Sadaqa ibn Yasar that al- Mughira ibn Hakim saw Abdullah ibn Umar sit back from the two sajdas of the prayer onto the top of his feet. When he had finished, al- Mughira mentioned it to him, and Abdullah ibn Umar explained, "It is not a sunna of the prayer. I do it because I am ill."
