Sayyiduna Ma'qil bin Yasar (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Act upon the Book of Allah and do not deny anything of it. Whatever of it seems unclear to you, ask the people of knowledge about it and they will inform you. And believe in the Torah and the Injil (Gospel), for in it (the Book of Allah) there is clear explanation, and it is an intercessor, and what it makes lawful is to be affirmed as true."
