Hasan Al Basri (R.A) reported that the Messenger of Allah (SAW) said, “The energy of the Ulama is care and help while the energy of fools is to quote.” (Kanz, Vol.10, Pg.249, Hadith No.29337, Published by Mu assasatur Risaalah)
Ibn Umar (R.A) said, the Messenger of Allah (SAW) said, “The best of all worship is the understanding of religion and the best thing in religion is the cultivation of piety.” (Majma oz Zawaid, Pg.159, Vol.1, Hadith No.479, Published by Darul Kutub Ilmiyah)
“All humans are dead except those who have knowledge; and all those who have knowledge are asleep, except those who do good deeds; and those who do good deeds are deceived, except those who are sincere; and those who are sincere are always in a state of worry.” (Imam Ash-Shafi [R.A])
“One who acts without knowledge is like one who travels off the path; and the one who acts without knowledge corrupts more than he rectifies. So seek knowledge in a way that does not harm your worship, and seek to worship [Allah] in a way that does not harm [your seeking of] knowledge. For verily, there were people (the Khawarij extremists) who sought to worship [Allah] but abandoned knowledge until they attacked the Ummah of Muhammad (SAW) with their swords. But if they had sought knowledge, it would not have directed them to do what they did.” (Hasan Al-Basri [R.A])
