The title given to Surah al-Baqarah’s 255th ayah by Prophet Muhammad ﷺ is “Ayat al Kursi”
Recite it after every prayer
Rasool Allah ﷺ said, “Whoever recites Aayatul Kursi after every Fard (Fard Salat). Only death is keeping him/her from entering Jannah. (As soon as he/she dies, will enter Jannah)
(Sunnan Nasai’i al Kubra, (6/30), At-Tabrani in his Al-Kabeer (8/114), Ibn Sunni in Amal al Yawm wal Layla (Page. 43), Imam al-Haythami in Majma az-Zawaid (10/106) where he declared the chain as “HASAN (FAIR)” and others)
It’s in another Hadith that Reciting Ayatul Kursi after one Fard (Fard Salat) will stay in Allah’s protection until the next Salat.
(Tibrani Fil Kabeer, A’n Alhasan Bin Ali Radiallahu Anhu)
Benefit to our Home and Children
Imam al-Mahamli (rah) narrates in his “Fawaid” from Ibn Masud (RadiAllahu Anhu): A man said: O Messenger of Allah ﷺ teach me something through which Allah will benefit me. The Prophet ﷺ said: Recite Ayat al Kursi, Allah will protect you, your children, also protect your house rather even the houses which are near to yours [Imam Jalal ud-din Suyuti in Dur ul Munthur, (2/6)]
Imam Bayhaqi (rah) states that the one who recites Ayatul Kursi before falling asleep, Allah Ta’ala gives protection to his/her home and his/her Family.
(Marqat Sharah Mishkaat, Mulla Ali Qaderi, vol. 2 pp. 583)
Protection Against Evil Jinns
Imam Nasai’i, Abu Ya’la, Ibn Hibban, Abu Shaykh in his Al-Azmah, Tabarani, Hakim who declared it Sahih, Abu Nua’ym and Baihaqi in his Dalail narrate from Ubay ibn Ka’b (RadiAllahu Anhu) that he used to have a field of dates and he used to guard it but as time passed by he kept less watch over it. One night he planned to guard it, but he saw an (animal) in shape of a young boy. Ubay Ibn Ka’b offered him greetings and he replied back. Ibn Ka’b asked him whether he was a human or Jinn? He replied: He was Jinn! Ubayy asked him to show his hand, Ubayy saw that his hand was like that of a dog and it had hair on it like dog does. Ubayy asked: Are Jinns created in this fashion? He replied: Some Jinns are even more stranger than me. Ubayy asked: Who compelled you to do this (i.e. steal from my field) he replied: I have heard that you love to give Sadaqa so I thought of taking (stealing) something from you. Ubayy asked: What is it that can protect us from you? The Jinn replied: “Ayat al Kursi” which is in Surah al-Baqarah, whosoever recites it in the evening will be safe from our Sharr till the morning, and whosoever recites it in the morning he will be safe from us till evening. On next morning Ibn Ka’b went to the Prophet (Peace be upon him) and told him about this, the Prophet (Peace be upon him) said: The “Khabeeth told the truth”
[Imam Jalal ud-din Suyuti in Tafsir Dur ul Munthur, Volume No.2, Page No. 5]
It’s in another Hadith that Jinns and Shaitans do not come close to the house in which Ayatul Kursi is recited.
(Tirmizi Altargheeb Wal Tarheeb Lilmanzari vol.2 pp.631)
Hadrat A’isha Radiallah Anha states that a person arrived in the court of Nabi kareem ﷺ and complained that there is no Barkat (Blessings) in anything in his home. Rasool Allah ﷺ said, “You do not recite Ayatul Kursi, whichever Food and Curry you will recite Ayatul Kursi on, Allah Tala will give Blessings on that Food and Curry.
