Ibn Majah

Benefits and Issues:

➊
During the time of Ali radi Allahu anhu, some people spread false statements about him.
Ali radi Allahu anhu refuted these false beliefs to the utmost extent possible.

➋
It is commonly claimed about Ali radi Allahu anhu that the Messenger of Allah sallallahu alayhi wa sallam granted him “inner knowledge” (‘ilm al-batin), which is different from the apparent knowledge of the Shari‘ah.
The current Sufi orders are also based on this concept.
This is an incorrect belief.
Whatever the Messenger of Allah sallallahu alayhi wa sallam has stated regarding the purification of the soul (tazkiyat al-nafs) is all present in the books of hadith.
This is not some secret knowledge.

➌
“Ilm al-jafr” is also attributed to Ali radi Allahu anhu,
through which, in people’s imagination, they come to know hidden matters of the past and future.
All of this is baseless.
To accept anyone other than Allah as a knower of the unseen (‘alim al-ghayb) is a denial of many verses of the Qur’an.

➍
To reflect and ponder upon the Noble Qur’an and to discover scholarly points is a great blessing.
To acquire this knowledge and to adorn one’s practical life in accordance with it is the real objective.

➎
The noble Companions radi Allahu anhum used to write down and preserve the Prophetic hadith, because they considered it an essential part of the Shari‘ah.
And they acted upon it.

➏
If a Muslim kills a dhimmi (non-Muslim under Muslim protection), then he will not be killed in retribution (qisas); however, blood money (diyah) can be taken.
