Some of the people thought that before he died, the Prophet (blessings and peace of Allah be upon him) left a will containing secret knowledge to his cousin ‘Ali ibn Abi Talib (may Allah be pleased with him). In this report, ‘Ali (may Allah be pleased with him) clearly tells us that all of that is contrary to reality, as the Prophet (blessings and peace of Allah be upon him) did not leave anything behind except the Qur’an and his Sunnah, and the ability to understand the Qur’an that Allah may grant to an intelligent and knowledgeable Muslim. Thus intelligence and ability to understand is regarded as another level, after learning and memorizing the Book of Allah, because by understanding it, meanings and rulings become clear. Alongside the Qur’an, we may include understanding of the Sunnah and deriving rulings from it. The phrase “understanding that may be granted to any Muslim man” highlights the fact that this understanding is not something exclusive or a monopoly for any one person; rather this understanding is something that any Muslim may have, and it is something that is granted by Allah (may He be glorified and exalted), as He says: {And We gave understanding of the case to Solomon} [al-Anbiya’ 21:79]. Understanding is a blessing that Allah may bestow upon any of His slaves. Then ‘Ali (may Allah be pleased with him) mentions some issues that were written on a sheet; the word refers to something on which words are written, no matter what it is made of, such as leather, palm leaves and the like. This document contained Islamic rulings that the Prophet (blessings and peace of Allah be upon him) had not given exclusively to him; rather others also knew about them. The Prophet (blessings and peace of Allah be upon him) would not have concealed anything of the religion of Allah from people and given it exclusively to some of his family. The issues mentioned on this sheet include ‘aql and diyah; these terms refer to blood money, which is a set amount of wealth, as stipulated in Islamic teachings, which is to be given by the relatives of the killer to the family of the one who was killed. It is called ‘aql because they used to hobble (ya‘qilun) the camels in the courtyard of the family who were entitled to the blood money [which was given in the form of camels]. What is meant is that the rulings on blood money, and the number, types and ages of camels to be given [were written in that document]. The document also contained information on the ransom of prisoners. What is referred to is Muslim prisoners, as it is obligatory to strive to ransom them and secure their release by all permissible means, whether by paying money or otherwise. And the document stated that “no Muslim should be killed in retaliation for a disbeliever.” What is meant is that if a believer kills a disbeliever who is in a state of war against the Muslims, then there is no retaliatory punishment (qisas) in this case; this is different from the case of a disbeliever who has a covenant with the Muslims and is under Muslim protection. And in some reports, other issues and instructions are also mentioned. This hadith demonstrates the falseness of the claims invented by the Rafidis and Shia who said that the Prophet (blessings and peace of Allah be upon him) bequeathed to ‘Ali (may Allah be pleased with him) the secrets and foundations of knowledge, and knowledge of the unseen, that he did not tell to anyone else. It indicates that the Book of Allah is the source of knowledge, and that understanding of knowledge should only be based on the Qur’an and on the hadiths of the Messenger of Allah (blessings and peace of Allah be upon him) which explain it. It indicates that the knowledgeable person may derive from the Qur’an, on the basis of his own understanding, something that was not referred to in the books of tafsir. But that is on condition that it is in accordance with the basic principles of Islam..
