Musannaf Ibn Abi Shaybah 37024 — Reports from our Prophet

Sayyiduna al-Mustawrid (may Allah be pleased with him), who belonged to Banu Fihr, said: I heard the Messenger of Allah (peace and blessings be upon him) say: By Allah Almighty, (the likeness of this world) in (comparison with) the Hereafter is as if one of you were to dip his finger in the sea and take it out, then see how much has come out (of the water of that sea, clinging to his finger) (the status of the water on the finger in comparison with the water of the sea is the status of this world in comparison with the Hereafter).
