If knowledge is useful without actions, Allah, the Exalted would never have dispraised the people of the book, and if actions were useful without devotion, He would never have dispraised the hypocrites.
(Imam Ibn Al-Qayyim – Al-Fawa’Id – A Collection Of Wise Sayings pg 54. )
‘Alee ibn Abee Taalib (radhi Allaahu anhu) said to Kumail ibn Ziyaad,
Knowledge is better than wealth. Knowledge is a protection for you, whereas it is you that has to protect wealth. The zakaat of knowledge is action, whereas spending decreases wealth. And love of the Scholar is part of the Religion. Knowledge brings about obedience for the Scholar in his own lifetime and causes him to have good repute after his death, whereas the benefit of wealth ceases when it passes away. The hoarders of wealth have died even though they are still alive, whereas the Scholars remain for as long as time remains – their persons are lost, but their examples remain in the hearts.
Reported by Abu Nu’aym in Hilyatul-Awliyaa (1/79-80), al-Khateeb al-Baghdaadee in al-Faqeeh wal-Mutafaqqih (1/49-50) and Ibn Katheer in al-Bidaayah wan-Nihaayah (9/47).
The Advice of ‘Alee (radiallaahu ‘anhu)
Shaykh Albanee, may Allaah have mercy on him, said,
“So aspire, O Muslim, to know your Islaam from your Lord’s Book and your Prophet’s Sunnah. And don’t say, ‘So and so said.’ For verily, the Truth is not known by the men–nay, know the Truth, you will recognise the men.’
Ibn Mas’ud –(radiyallaahu ‘anhu) – would advise his students,
If your intention is one of these three, do not seek knowledge:
To shame the ignorant, or
To argue with the Fuqahaa’ (scholars), or
To cause people to turn their faces in your direction.
Intend with your actions and words that which is with Allaah, for indeed that which is with Allaah shall remain and everything else shall perish.
Imaam Ibn Seereen (rahimahullaah) said :
‘Indeed, This knowledge Is Deen,
So Look To The One You Take Your Deen From
