All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
A good statement among Muslims states that 'Know the truth, you know its followers'; and 'we weigh and recognize men by truth, not truth by men.'
Allah, The Exalted, has not granted infallibility to any human being except His Prophets and Messengers. Thus, a Muslim has to look after the truth and Sunnah and never be deeply attracted to some person since Allah has granted some people good knowledge and blessings, but He has not specified any to be followed, except His Prophets and Messengers.
Shaykh al-Islam Ibn Taymiyyah said: “It is not possible for somebody to have comprehensive knowledge of the Prophetic Hadeeth. Only the four well-guided successors could achieve such knowledge since they spent their lives with the Prophet especially Abu Bakr who was used to accompanying him most of the time; he even spent nights discussing matters that concern Muslims. Also, ‘Umar used to spend most of the time with the Prophet and his dearest friend Abu Bakr .
The Prophet often used to say: “I entered with the company of Abu Bakr and ‘Umar, and went out with the company of Abu Bakr and Umar.”
In spite of this, when Abu Bakr was asked about the portion of the grandmother in the inheritance, he said: “I find nothing in the Quran nor the Sunnah of the Prophet but you have to ask people.” When the person asked the people, al-Mugheerah and Muhammad Ibn Maslamah said: “The Prophet allocated for her one-sixth.”
Moreover, ‘Umar ibn al-Khattaab did not know the Sunnah concerning seeking the permission to enter someone's house until Abu Moosa taught him.
Ibn Taymiyyah added: 'Many similar narrations were reported from the Prophet’s Companions in this concern.
There are so many narrations in this concern from the Prophet’s Companions and more that came after them. They were the best scholars among the Muslim Ummah and it is natural to find that the late scholars cannot have a comprehensive knowledge and this issue needs no clarification.”
As a result, a Muslim has to honor the scholars who follow the Sunnah of the Prophet to believe that they are a source of good, light and blessing due to the knowledge of the Sharee'ah which they have. They can benefit from them and should avoid being excessive in praising any of them (scholars), since this leads one to be among the followers of innovation.
Consider the following beautiful saying of Ibn Mas'ood : “Whoever likes to follow the Sunnah should follow those who died (from among the companions and well-known good Imams) since following a living one may lead to something wrong!”
Allah knows best.
