It is narrated from Sayyiduna Husayn (may Allah be pleased with him), he says: I said, "O Messenger of Allah! I have become a Muslim, so which supplication should I make?" The Prophet (peace and blessings be upon him) said: "Supplicate like this: «اللّٰهُمَّ إِنِّي أَسْتَهْدِيكَ لِأَرْشَدِ أَمْرِي وَأَعُوذُ بِكَ مِنْ شَرِّ نَفْسِي» 'O Allah! I ask You for guidance towards my very best deeds, and I seek refuge with You from the evil of my own self.'"
