Abdur Rahman bin Ghanm narrated that Jibreel (peace be upon him) descended to the Messenger of Allah (peace and blessings be upon him), split open his chest, and then said: "It is a very strong heart in which there are two listening ears and two seeing eyes. Muhammad is Allah’s last Messenger and the Gatherer (Hashir). Your character is pure, your tongue is truthful, and your soul is content." Imam Darimi said: The meaning of «وكيع» is "strong."
