Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ عَنْ عَاصِمِ بْنِ كُلَيْبٍ عَنْ مُحَارِبِ بْنِ دِثَارٍ قَالَ رَأَيْتُ ابْنَ عُمَرَ يَرْفَعُ يَدَيْهِ كُلَّمَا رَكَعَ وَكُلَّمَا رَفَعَ رَأْسَهُ مِنْ الرُّكُوعِ قَالَ فَقُلْتُ لَهُ مَا هَذَا قَالَ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا قَامَ فِي الرَّكْعَتَيْنِ كَبَّرَ وَرَفَعَ يَدَيْهِ.
English Translation
Muhammad ibn Fudayl told us, from Asim ibn Kulayb, from Muharib ibn Dithar, who said: I saw Ibn Umar raising his hands every time he bowed and every time he raised his head from bowing. I said to him: What is this? He said: The Prophet (peace and blessings be upon him), when he stood up after the two rak'ahs, would say the takbir and raise his hands.
