Arabic hadith text
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 Abdullahibn Umar said, "O Allah, make me one of the leaders of the people oftaqwa ."
Allahumma jalniy min a'imati'l-mutaqin.
