Question: What is the most reliable book which discusses the signs of the [Last] Hour and the trials and tribulations?
Response: The most reliable book in that, after the Book of Allaah (Subhaanahu wa Ta’aala), is «Saheeh al-Bukhaaree» and «Saheeh Muslim», then «Sunan Abee Daawood» and «Sunan an-Nasaa.ee» and «Jaami’ at-Tirmidhee» and «Sunan Ibn Maajah», and the most comprehensive of them all is «al-Bidaayah wan-Nihaaya» by Ibn Katheer, and «Ittihaaf al-Jamaa’ah fee Akhbaar al-Fitan wal-Malaahim wa Ashraat as-Saa’ah» by Shaykh Hamood ibn ‘Abdullaah at-Tuwayjaree.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
