Hadith on Salat: Sitting properly in prayer unless unable

Abdullah ibn Abdullah reported: I saw Abdullah ibn Umar, may Allah be pleased with him, sitting cross-legged in the prayer, so I did so too, as in that day I was young. Ibn Umar forbade me from doing it and he said, “Indeed, the Sunnah of prayer is to prop up the right foot and tuck the left foot.” I said, “But I saw you sitting cross-legged.” Ibn Umar said, “My feet cannot support me.”

Grade: Sahih (authentic) according to Al-Bukhari

Abu Umar said, “As for the correct position, it is not permissible to sit cross-legged in the prayer according to the consensus of the scholars. Likewise, they came to a consensus that whoever does not have the ability to sit properly in prayer should act within his ability. Allah does not hold a soul responsible except for what is within its capacity.”

عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ قال رأيت عَبْدَ اللَّهِ بْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا يَتَرَبَّعُ فِي الصَّلَاةِ إِذَا جَلَسَ فَفَعَلْتُهُ وَأَنَا يَوْمَئِذٍ حَدِيثُ السِّنِّ فَنَهَانِي عَبْدُ اللَّهِ بْنُ عُمَرَ وَقَالَ إِنَّمَا سُنَّةُ الصَّلَاةِ أَنْ تَنْصِبَ رِجْلَكَ الْيُمْنَى وَتَثْنِيَ الْيُسْرَى فَقُلْتُ إِنَّكَ تَفْعَلُ ذَلِكَ فَقَالَ إِنَّ رِجْلَيَّ لَا تَحْمِلَانِي

793 صحيح البخاري أبواب صفة الصلاة باب سنة الجلوس في التشهد

وَقَالَ أَبُو عُمَرَ وَأَمَّا الصَّحِيحُ فَلَا يَجُوزُ لَهُ التَّرَبُّعُ فِي الصَّلَاةِ بِإِجْمَاعٍ مِنَ الْعُلَمَاءِ وَكَذَلِكَ أَجْمَعُوا عَلَى أَنَّهُ مَنْ لَمْ يَقْدِرْ عَلَى هَيْئَةِ الْجُلُوسِ فِي الصَّلَاةِ أَتَى عَلَى حَسَبِ مَا يَقْدِرُ، لَا يُكَلِّفُ اللَّهُ نَفْسًا إِلَّا وُسْعَهَا
