Imam Ja‘far al-Ṣadiq (as): Many a seeker of the world who did not achieve it, and many a person who, as soon as he achieved the world, departed from it; so let not seeking the world preoccupy you from performing good deeds, and seek the world from its granter and owner, for many a covetous person for the world who was struck down by it, who was preoccupied by what he had secured of this world from seeking his hereafter until his life came to an end and his death overtook him. al-Kāfī
