Authentic Prophetic duaلاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ، وَلاَ مُعْطِيَ لِمَا مَنَعْتَ، وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الجَدُّ

None has the right to be worshipped but Allah alone, who has no partner. His is the dominion and His is the praise, and He is Able to do all things.

5.Ayat al-Kursi after every obligatory prayer
From the Quranٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ ۚ لَا تَأْخُذُهُۥ سِنَةٌ وَلَا نَوْمٌ ۚ لَّهُۥ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۗ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُۥٓ إِلَّا بِإِذْنِهِۦ ۚ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ ۖ وَلَا يُحِيطُونَ بِشَىْءٍ مِّنْ عِلْمِهِۦٓ إِلَّا بِمَا شَآءَ ۚ وَسِعَ كُرْسِيُّهُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ ۖ وَلَا يَـُٔودُهُۥ حِفْظُهُمَا ۚ وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُ

Allāh - there is no deity except Him, the Ever-Living, the Self-Sustaining. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursī extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great. (Saheeh International (quran.com); transliteration: quran.com word by word)
The Prophet ﷺ said that nothing prevents whoever recites Ayat al-Kursi after every obligatory prayer from entering Paradise except death. (Sahih al-Jami' 6464 · Sahih (al-Albani))
Al-Mundhiri and al-Haythami said one of its chains is sound, Ibn Kathir said its chain meets al-Bukhari's conditions, and Ibn Baz and Shu'ayb al-Arna'ut accepted it. Ibn al-Jawzi listed it among fabricated reports; Ibn Hajar said he was mistaken.

Say, "He is Allāh, [who is] One, Allāh, the Eternal Refuge. He neither begets nor is born, Nor is there to Him any equivalent." · Say, "I seek refuge in the Lord of daybreak From the evil of that which He created And from the evil of darkness when it settles And from the evil of the blowers in knots And from the evil of an envier when he envies." · Say, "I seek refuge in the Lord of mankind, The Sovereign of mankind, The God of mankind, From the evil of the retreating whisperer - Who whispers [evil] into the breasts of mankind - From among the jinn and mankind".
