Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "The people of La ilaha illallah (there is no god but Allah) will feel no dread at death, nor in the graves, nor at the time of being raised again. It is as though I am looking at them even now, when the Cry (of the blowing of the Trumpet) comes, shaking the dust off their heads and saying (as mentioned in the Qur'an in these words): 'All praise belongs to Allah, who has removed grief from us.'"
Al-Tabarani recorded it; its chain contains a group of narrators whom I do not know.
