Be careful how you behave with them after me.

Be careful how you behave with them after me.” This tradition is one of the traditions which expresses the authority of the Household of the Prophet in presenting pure Islam. Here is a list of books recording this tradition, but we should note that these are just some samples of Sunni scholars' works and there are many other books by Shi’s and Sunni scholars which include this tradition: Sahih Muslim, the Book of fadail (merits) of ‘Ali ibn Abi Talib, Vol.

7, p.122, Sahih al-Tirmidhi, Vol.5, p.328, Khasais a by Imam Nesa'i, p.21; Musnad by Imam Ahmad ibn Hanbal Vol.3, p.17; Kanz al-'Ummal, Vol. 1, p.154; Al-Tabaqat al-Kubra by Ibn Sa'd, Vol.2, p.194; Jami' at-Usul by Ibn Athir Vol. 1, p.187; AI-Jami' al-Saghir by Al-Suyuti, Vol.1, p.353; Usd al-Ghabah by Ibn Athir Vol.2, p.12; Tarikh al-Dimashq by Ibn 'As5kir, Vol.5, p.436.; Al- Tafsir by Thn Kathrr, Vol.4, p.113. We should take care of our beliefs: basic ones and derivative ones.

if a person is not expert or skilled in discovering Islamic thoughts and concepts through the Glorious Qur'an or the traditions he must not interpret them according to his desires or weak understanding and he must not rely on those people who are not of sufficient knowledge and expertise. To use their books or sayings is like taking medicine according to the prescriptions of false physicians. Thus, understanding the details of the beliefs is like understanding practical laws.

According to Islam our happiness is not only based on our faith or beliefs. Deeds as well as virtues bear on our happiness. Islamic practical laws are to guide us in the realm of actions especially when our intellect or conscience is uncertain. Every person can learn jurisprudence and the related sciences and become a mujtahid. Then he can rely on his own understanding of the laws. But it is a difficult process and needs much cleverness, long work and practice.

Those who are not prepared for this job have two other possibilities. They can exercise precaution. For example, when they are in doubt about whether something is obligatory or recommended they must do it, or when they do not know whether something is forbidden or allowed they must not do it. To behave in this way is very difficult and even impossible for those who are not learned in jurisprudence.

The second possibility is to imitate or follow a person who is proved to be a mujtahid or the most learned and at the same time just, trustworthy, insightful and the like.
