Muwatta Malik · Hadith 511

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، قَالَ اللَّهُمَّ اجْعَلْنِي مِنْ أَئِمَّةِ الْمُتَّقِينَ ‏.‏

Yahya related to me from Malik that he had heard that Abdullah ibn Umar said, "O Allah, make me one of the leaders of the people of taqwa ." Allahumma jalniy min a'imati'l-mutaqin
