Sahih Muslim 2725
Sahih Muslim · Book 48: The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness · Supplications [Of The Prophet (SAW)]
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:
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 .
Say:" O Allah, I beg of Thee righteousness and adhering to the straight path."
