Narrated by Sayyidna Ibn 'Abbas (Radhi-Allahu Anh: Allah be pleased with him), the Holy Prophet (Sallallahu 'Alayhi Wasallam: Peace be upon him) said that:
"Allah Almighty has sent forth these two verses out of the treasures of Paradise and the 'Rahman (merciful) had already written them by His own hand two thousand years earlier than the creation of all things and beings. One who is able to recite them after the Salah of 'Isha', they will stand for Tahajjud in his case."
As it appears in the Mustadrak of al-Hakim and in Bayhaqi, the Holy Prophet Sallallahu 'Alayhi Wasallam: Peace be upon him said that Allah Almighty has concluded Surah al-Baqarah with these two verses, which have been given to me in His grace from out of the special treasure that lies under the 'Arsh' (Divine Throne). Therefore, you should make special effort to learn these verses, and at the same time, teach your women and children how to recite them. This is why Sayyidna 'Umar and Sayyidna 'Ali (R.A) said that they thought that anybody who has any sense in him would never go to sleep without having recited these two verses.
Abu Mas’ud reported: The Prophet, peace and blessings be upon him, said, “Whoever recites in the night the last two verses of Surah Al-Baqarah will be sufficed by them.”
