The title of verse 255 of Sūrah al-Baqarah, the second chapter of the Qurʾān which describes God’s majesty. 

This verse is considered as being the greatest verse and is often recited when seeking protection, especially prior to travel. 

Based on numerous ahadith, the Shi’ah Imams have advised the believers to also read verses 256 and 257 to “complete” what is found in verse 255 and in some acts of worship which require the believer to recite Ayat al-Kursi, there is a reference to also include verses 256 and 257.
