All the knowledge of people are in four categories

Hawzah News Agency - Ali ibn Ibrahim has narrated from his father from al-Qasim ibn Muhammad from al-Minqari from Sufyan ibn ‘Uyaynah who has said the following. “(Imam) abu ‘Abdallah who said,

وَجَدْتُ عِلْمَ النَّاسِ كُلَّهُ فِي أَرْبَعٍ أَوَّلُهَا أَنْ تَعْرِفَ رَبَّكَ وَالثَّانِي أَنْ تَعْرِفَ مَا صَنَعَ بِكَ وَالثَّالِثُ أَنْ تَعْرِفَ مَا أَرَادَ مِنْكَ وَالرَّابِعُ أَنْ تَعْرِفَ مَا يُخْرِجُكَ مِنْ دِينِكَ.

‘I have found all the knowledge of people in four categories: The knowledge that would teach you about your Lord. (b) The knowledge that would teach you what the Lord has done for you. (c) The knowledge that would teach you what the Lord wants from you. (d) The knowledge that would teach you what destroys your religion.’”
