This hadith has been narrated on the authority of 'Asim b. Kulaib with the same chain of transmitters that Allah's Messenger (ﷺ) said to me:Say:" O Allah, I beg of Thee righteousness and adhering to the straight path."
وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا عَبْدُ اللَّهِ، - يَعْنِي ابْنَ إِدْرِيسَ - أَخْبَرَنَا عَاصِمُ بْنُ كُلَيْبٍ، بِهَذَا الإِسْنَادِ قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم " قُلِ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْهُدَى وَالسَّدَادَ " . ثُمَّ ذَكَرَ بِمِثْلِهِ .
