اَللَّهُمَّ إِنِّي أَسْأَلُكَ الْهُدَى وَالسَّدَادَ

Allaahumma inni as'alukal huda was-sadaad

O Allah, I beg of Thee righteousness and adhering to the straight path. [He (ﷺ) then said to Ali (RA)] when you make a mention of right guidance, keep in mind the right path and when you consider of the straight (path), keep in mind the straightness of the arrow.
