AYAT AL KURSI
It is mentioned in Misbah of Kafami from the Holy Prophet (s.a.w.a.) that one who recites Ayatul Kursi regularly is given by Allah wisdom to his heart, faith, sincerity, reliance and honour. One who writes it with Zamzam water or rain water is cured of every ailment of his body. He would also be safe from instigations of Satan and forgetfulness. One who wears it as an amulet, is protected from wild animals, reptiles, magic and every disease. One who recites it repeatedly would remain safe from divine chastisement.

اللّٰهُ لَاۤ اِلٰهَ اِلَّا هُوَ الْحَىُّ الْقَيُّوْمُ۬ ۚ  لَا تَاْخُذُهٗ سِنَةٌ وَّلَا نَوْمٌ‌ؕ لَهٗ مَا فِى السَّمٰوٰتِ وَمَا فِى الْاَرْضِ‌ؕ مَنْ ذَا الَّذِىْ يَشْفَعُ عِنْدَهٗۤ اِلَّا بِاِذْنِهٖ‌ؕ يَعْلَمُ مَا بَيْنَ اَيْدِيْهِمْ وَمَا خَلْفَهُمْ‌ۚ وَلَا يُحِيْطُوْنَ بِشَىْءٍ مِّنْ عِلْمِهٖۤ اِلَّا بِمَا شَآءَ ۚ وَسِعَ كُرْسِيُّهُ السَّمٰوٰتِ وَالْاَرْضَ‌‌ۚ وَلَا يَئُوْدُهٗ حِفْظُهُمَا ‌ۚ وَ هُوَ الْعَلِىُّ الْعَظِيْمُ﴿255﴾‏

255.Allahu laaa ilaaha illaa Huwal Haiyul Qaiyoom; laa taakhuzuhoo sinatunw wa laa nawm; lahoo maa fissamaawaati wa maa fil ard; man zal lazee yashfa'u indahooo illaa bi-iznih; ya'lamu maa baina aydeehim wa mww khalfahum wa laa yuheetoona bishai'im min 'ilmihee illaa bimaa shaaa'; wasi'a Kursiyyuhus samaawaati wal arda wa laa ya'ooduho hifzuhumaa; wa Huwal Aliyyul 'Azeem

255.Allah—there is no god except Him—is the Living One, the All-sustainer. Neither drowsiness befalls Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that may intercede with Him except with His permission? He knows what is before them and what is behind them, and they do not comprehend anything of His knowledge except what He wishes. His seat embraces the heavens and the earth and He is not wearied by their preservation, and He is the All-exalted, the All-supreme.

لَاۤ اِكْرَاهَ فِى الدِّيْنِ‌ۙ  قَد تَّبَيَّنَ الرُّشْدُ مِنَ الْغَىِّ‌ۚ فَمَنْ يَّكْفُرْ بِالطَّاغُوْتِ وَيُؤْمِنْۢ بِاللّٰهِ فَقَدِ اسْتَمْسَكَ بِالْعُرْوَةِ الْوُثْقٰىۗ لَا انْفِصَامَ لَهَا‌‌ ؕ وَاللّٰهُ سَمِيْعٌ عَلِيْمٌ﴿256﴾‏

256.Laaa ikraaha fid deeni qat tabiyanar rushdu minal ghayy; famai yakfur bit Taaghooti wa yu'mim billaahi faqadis tamsaka bil'urwatil wusqaa lan fisaama lahaa; wallaahu Samee'un 'Aleem

256.There is no compulsion in religion: rectitude has become distinct from error. So one who disavows fake deities and has faith in Allah has held fast to the firmest handle for which there is no breaking; and Allah is all-hearing, all-knowing.

اَللّٰهُ وَلِىُّ الَّذِيْنَ اٰمَنُوْا يُخْرِجُهُمْ مِّنَ الظُّلُمٰتِ اِلَى النُّوْرِ‌۬ ؕ  وَالَّذِيْنَ كَفَرُوْۤا اَوْلِيٰٓئُهُمُ الطَّاغُوْتُۙ يُخْرِجُوْنَهُمْ مِّنَ النُّوْرِ اِلَى الظُّلُمٰتِ‌ؕ اُولٰٓئِكَ اَصْحٰبُ النَّارِ‌‌ۚ هُمْ فِيْهَا خٰلِدُوْنَ۠ ﴿257﴾‏

257.Allaahu waliyyul lazeena aamanoo yukhrijuhum minaz zulumaati ilan noori wallazeena kafarooo awliyaaa'uhumut Taaghootu yukhrijoonahum minan noori ilaz zulumaat; ulaaa'ika Ashaabun Naari hum feehaa khaalidoon

257.Allah is the wali of the faithful: He brings them out of darkness into light. As for the faithless, their awliya are the fake deities, who drive them out of light into darkness. They shall be the inmates of the Fire, and they will remain in it [forever].
