Verse 255 of Surah-e-Baqarah (chapter: The cow) in holy Quran is called Ayat Al-Kursi: “Allah! There is no god but He – the Living, The Self-subsisting, Eternal. No slumber can seize Him Nor Sleep. His are all things in the heavens and on earth. Who is there can intercede in His presence except as he permitteth? He knoweth what (appeareth to His creatures As) before or after or behind them. Nor shall they compass Aught of his knowledge Except as He willeth. His throne doth extend over the heavens and on earth, and He feeleth No fatigue in guarding and preserving them, For He is the Most High, The Supreme (in glory).”
The benefits of Ayat Al-Kursi are:

1. Holy prophet (SAWW) said: whoever recites the first 4 ayats of Surae Baqarah, then Ayatul Kursi and then the last 3 ayats of Surah e Baqarah, will not be inflicted with any kind of difficulty in his wealth or himself, Satan will not come near him and he will not forget the Qur’an.

2. Holy Prophet (SAWW) said: Qur’an is a great word, and Surae Baqarah is the leader of the Qur’an and Ayatul Kursi is the leader of Surae Baqarah. In Ayatul Kursi there are 50 words and for each word there are 50 blessings and good in it.

3. One who recites Ayatul Kursi every morning will be in the protection, safety of Allah until the night.

4. If one ties this to ones wealth or children, they will be safe from Satan

5. Our Holy Prophet (SAWW) has said: These things increase ones memory: sweets, meat of an animal near the neck, Adas (Lentils), cold bread and recitation of Ayatul Kursi.

6. For those of our dear ones who have passed away, recitation of Ayatul Kursi and giving it as Hadiya to them, gives them light (noor) in the grave.

7. Frequent recitation makes ones own death easy.
