Something i found on a website online and wanted to share i hope some one learns something new :
The blessings of this verse (ayat al korsi) is apparent from this hadith narrated by Abu Hurayrah. He said:
The Messenger of Allah (s.a.w.) put me in charge of guarding the zakaah of Ramadaan. Someone came to me and started grabbing (taking illegally) handful of the food. I took hold of him and said, ‘I will take you to the Messenger of Allah (s.a.w.).’ He said, ‘I will teach you some words by means of which Allah will benefit you.’ I said, ‘What are they?’ He said, ‘When you go to your bed, recite this aayah: “Allah! Laa ilaaha illa Huwa (none has the right to be worshipped but He), Al-Hayyul-Qayyoom (the Ever Living, the One Who sustains and protects all that exists)…” [Surah al-Baqarah, 2:255]. Then Allah will appoint a guard for you who will stay with you and no Shaytan (devil) will come near you until morning.’ The Messenger of Allah (s.a.w.) asked me, ‘What did your prisoner do last night?’ I said, ‘O Messenger of Allah, he taught me something, and claimed that Allah would benefit me by it.’ He said, ‘What was it?’ I said, ‘He taught me to recite Aayat al-Kursiy when I go to bed, and said that no Shaytan would come near me until morning, and that Allah would appoint a guard for me who would stay with me.’ The prophet (s.a.w.) said, ‘He told you the truth, although he is an inveterate liar. That was the Shaytan’-[narrated by al-Bukhaari, 3101; Muslim, 505].
