The Messenger of Allah ﷺ said, "The believer in his grave is in a green meadow. His grave is widened for him to seventy cubits, and it is illuminated for him like the moon on the night of a full moon."Then he asked, "Do you know about whom this verse was revealed, 'Indeed, he will have a depressed life, and We will gather him on the Day of Resurrection blind' [Ta-Ha 20:124]? Do you know what the depressed life is?"They replied, "Allah and His Messenger know best."He said, "It is the punishment of the disbeliever in his grave. By the One in whose hand my soul is, ninety-nine tinnins are set upon him. Do you know what a tinnin is? It is seventy serpents, each serpent having seven heads. They sting him and tear at him until the Day of Resurrection."
عن رسول الله ﷺ قال: إن المؤمن في قبره لفي روضة خضراء، ويرحب له قبره سبعون ذراعا، وينور له كالقمر ليلة البدر، أتدرون فيما أنزلت هذه الآية: {فإن له معيشة ضنكا ونحشره يوم القيامة أعمى}؟ أتدرون ما المعيشة الضنكة؟ قالوا: الله ورسوله أعلم. قال: عذاب الكافر في قبره، والذي نفسي بيده إنه يسلط عليه تسعة وتسعون تنينا، أتدرون ما التنين؟ سبعون حية، لكل حية سبعة رؤوس يلسعونه ويخدشونه إلى يوم القيامة.
Narrated by Abu Yaala (6644), Ibn Hibban (3122, and this is his wording), and Bayhaqi in Adhab al-Qabr (80), all of them through the route of Abdullah bin Wahb, who said, Amr bin Harith informed me, that Abu Samh told him, from Ibn Hujayra, from Abu Hurairah, and he related it.Its chain is hasan due to what has been said about Abu Samh, who is Darraj bin Saman, whose hadith is graded hasan except when narrating from Abu Haytham.Bazzar (9407) also narrated it through another route, from Ibn Hujayra, in similar wording.
