عَنْ عَلْقَمَةَ عَنْ عَبْدِ اللَّهِ (بْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ) قَالَ: عَلَّمَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الصَّلَاةَ فَكَبَّرَ وَرَفَعَ يَدَيْهِ ثُمَّ رَكَعَ وَطَبَّقَ بَيْنَ يَدَيْهِ وَجَعَلَهُمَا بَيْنَ رُكْبَتَيْهِ، فَبَلَغَ سَعْدًا فَقَالَ: صَدَقَ أَخِي، قَدْ كُنَّا نَفْعَلُ ذَلِكَ ثُمَّ أُمِرْنَا بِهَٰذَا وَأَخَذَ بِرُكْبَتَيْهِ
It is narrated from Alqamah that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) taught us prayer. So he (peace and blessings be upon him) said the takbeer and raised his hands, then he bowed (in ruku‘) and placed his hands together between his knees. When Sayyiduna Sa'd (may Allah be pleased with him) came to know of this, he said: My brother (Ibn Mas'ud) has spoken the truth, but in reality, we used to do this, then we were commanded otherwise. Then, clarifying, he held his knees.
