Asma’ daughter of Abu Bakr said, “God’s messenger arose to deliver an address in which he mentioned the trial a man will endure in the grave. On his mentioning that, the Muslims gave a shout of dismay." Bukhari transmitted it thus, but Nasa’i added, “which prevented me from grasping what God's messenger had said. So when the clamour died down I said to a man near me, ‘God bless you, what did God’s messenger say at the end of his address?' He replied that he said he had had a revelation that the trial they would endure in their graves would approximate to that of ad-Dajjal."
