It is narrated from Sa'id bin al-Musayyab (may Allah have mercy on him) that the Prophet (peace and blessings be upon him) said: "These three were shown to me in Paradise in a tent of pearl, each of them on a throne." I saw the necks of Zayd and Ibn Rawahah turned aside (from the throne), while Ja'far was perfectly straight, with no turning in him. The narrator says: (The Prophet (peace and blessings be upon him)) asked, or he said: I was told that when death overcame those two, it was as if they turned away, or as if they turned their faces aside, whereas Ja'far did not do so. Ibn Uyaynah (may Allah have mercy on him) says: This is the occasion on which Ibn Rawahah said: "O soul, I swear that you shall surely descend (onto the battlefield), even if you obey with reluctance; for a long time you have sat at ease." And Sayyiduna Ja'far (may Allah be pleased with him) said: "How sweet is the fragrance of Paradise!"
