Dua for Mercy and Guidance
Allah has promised that He will guide those who seek His guidance and bestow His mercy upon them.
Verily We have sent down revelations and explained them. Allah guides whomsoever He wills to a straight path.
[Surah An-Nur,24-46]
Every Messenger of Allah guided their people on the right path including Ibrahim Alaihisalam, Dawood Alaihisalam, Moosa Alaihisalam, and Isa Alaihisalam.
The last messenger was Prophet Muhammad (saw), to whom the Qur'an was revealed.
This dua for mercy and guidance should be recited after every Salat to ask Allah for His Mercy and Guidance in all worldly matters.
Rabbana La Tuzigh Qulubana Ba'da iz Hadaitana Wahab Lana Min Ladunka Rahmatan Innaka Antal Wahhabu
[Surah Ali' Imran 3:8]
O Allah! Let not our hearts deviate after You have guided us to the right path; grant us Your mercy, You are indeed the Most Generous.
