Muwatta Malik #198
Prayer
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، أَنَّهُ سَمِعَ عَبْدَ اللَّهِ بْنَ عُمَرَ، وَصَلَّى، إِلَى جَنْبِهِ رَجُلٌ فَلَمَّا جَلَسَ الرَّجُلُ فِي أَرْبَعٍ تَرَبَّعَ وَثَنَى رِجْلَيْهِ فَلَمَّا انْصَرَفَ عَبْدُ اللَّهِ عَابَ ذَلِكَ عَلَيْهِ فَقَالَ الرَّجُلُ فَإِنَّكَ تَفْعَلُ ذَلِكَ . فَقَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ فَإِنِّي أَشْتَكِي .
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."
