Sayyiduna Abu Mas'ud al-Ansari (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Whoever recites at night these last two verses of Surah al-Baqarah, from 'The Messenger believes in what has been sent down to him from his Lord' to the end of the surah, they will suffice him." Abdur-Rahman bin Yazid said: I went to Sayyiduna Abu Mas'ud al-Ansari (may Allah be pleased with him) while he was performing tawaf, and I asked him about this hadith, and he narrated this hadith to me from the Messenger of Allah (peace and blessings be upon him).
