Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ إِسْحَاقَ قَالَ أَخْبَرَنِي حَمَّادُ بْنُ سَلَمَةَ عَنْ قَتَادَةَ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْ الْإِقْعَاءِ وَالتَّوَرُّكِ فِي الصَّلَاةِ قَالَ عَبْد اللَّهِ كَانَ أَبِي قَدْ تَرَكَ هَذَا الْحَدِيثَ.
English Translation
Yahya ibn Ishaq told us, he said: Hammad ibn Salama informed me, from Qatada, from Anas ibn Malik, that the Messenger of God, peace and blessings be upon him, forbade squatting on the heels and sitting sideways in prayer. Abdullah said: My father had abandoned narrating this hadith.
