By Allah! I have excellent knowledge of delivering messages, fulfilling promises, and explaining the correct interpretation of verses, and we, the Ahl al-Bayt (of prophethood, peace be upon them), are the doors of knowledge and understanding and the bright paths of the Shariah. Be aware that the spirit of all the laws of religion is one, and its paths are straight. Whoever takes to them has reached the destination and benefited, and whoever remains has gone astray and (finally) become regretful and remorseful. Act for that day for which provisions are prepared and in which intentions will be tested. If one's own intellect, which is present with him, does not benefit him, then (others') intellects, which are distant and hidden from him, will be very helpless and incapable of benefiting. Fear the fire of Hell, whose heat is intense and whose depth is very great, and (where there is) iron jewelry to wear and (pus-filled) blood to drink. Yes! The person whose good mention Allah keeps alive among people, that is far better for him than that wealth whose heirs are made such people who do not even appreciate it.
