Sayyiduna Abdur-Rahman bin Ka'b bin Malik (may Allah be pleased with him) reports about Sayyiduna Ka'b (may Allah be pleased with him): When the time of his death drew near, Sayyidah Umm Mubashshir (may Allah be pleased with her) came to him and said: "Convey my greetings of peace to my son." Sayyiduna Ka'b said to her: "Have you not heard the Prophet (peace and blessings be upon him) saying: 'The soul of the believer is in the form of a bird, and it hangs on the trees of Paradise until it is raised up again on the Day of Resurrection'?" That woman replied: "Yes, but I had forgotten." (Allamah al-Haythami says:) I say: This hadith of Sayyiduna Ka'b (may Allah be pleased with him) is mentioned in the Sahih.
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are the narrators of the Sahih.
