وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، وَزَيْدَ بْنَ ثَابِتٍ، كَانَا يَقُولاَنِ مَنْ أَدْرَكَ الرَّكْعَةَ فَقَدْ أَدْرَكَ السَّجْدَةَ ‏.‏

Yahya related to me from Malik that he had heard that Abdullahibn Umar and Zayd ibn Thabit used to say, "Whoever catches the rukuhas caught the sajda." Translation Not Available
