malik:3-54Mālik > ʿAbd al-Raḥman b. al-Qāsim > ʿAbdullāh b. ʿAbdullāh b. ʿUmar

Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim that Abdullah ibn Umar told him that he used to see Abdullah ibn Umar cross his legs in the sitting position of the prayer.He said, "So I did the same, and I was young at the time. Abdullah ibn Umar forbade me and said, 'The sunna of the prayer is that you keep your right foot vertical and lay your left foot down.' I said to him, 'But you do the same (as I did).' He said, 'My feet do not support me.' "  

مالك:٣-٥٤وَحَدَّثَنِي عَنْ مَالِكٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ

أَنَّهُ أَخْبَرَهُ أَنَّهُ كَانَ يَرَى عَبْدَ اللَّهِ بْنَ عُمَرَ يَتَرَبَّعُ فِي الصَّلاَةِ إِذَا جَلَسَ قَالَ فَفَعَلْتُهُ وَأَنَا يَوْمَئِذٍ حَدِيثُ السِّنِّ فَنَهَانِي عَبْدُ اللَّهِ وَقَالَ إِنَّمَا سُنَّةُ الصَّلاَةِ أَنْ تَنْصِبَ رِجْلَكَ الْيُمْنَى وَتَثْنِيَ رِجْلَكَ الْيُسْرَى فَقُلْتُ لَهُ فَإِنَّكَ تَفْعَلُ ذَلِكَ فَقَالَ إِنَّ رِجْلَىَّ لاَ تَحْمِلاَنِّي

"عَنْ عَبْد الله بن عَبد الله بِن عُمَرَ قَالَ: صَلَّى ابن عُمَرَ فَتَرَبَّعَ، فَفَعَلْتُ ذَلِكَ وَأَنَا حَدِيثُ السِّنَّةِ فَقَالَ: وَلِمَ تَفْعَلُ ذَلكَ؟ قُلْتُ: فَإنَّكَ تَفْعَلهُ، قَالَ: إِنَّهَا لَيْستْ مِنْ سُنَّةِ الصَّلاَةِ وَلَكِن سُنَّة الصَّلاَةِ أَنْ تَثْنِىَ الْيُسْرَى وَتَنْصبَ الْيُمْنَى، وَإنِّى لاَ تَحْمِلُنِى رِجْلاَى".
