لا يَقبَلُ اللَّهُ عَمَلاً إلّا بِمَعرِفَةٍ ، ولا مَعرِفَةً إلّا بِعَمَلٍ ، فمَن عَرَفَ دَلَّتهُ المَعرِفَةُ عَلَى العَمَلِ ، ومَن لَم يَعمَلْ فلا مَعرِفَةَ لَهُ.

Allah does not accept any act without inner knowledge and inner knowledge only comes through prior action. So, whoever gains knowledge intrinsically, his knowledge will lead him to action, and whoever does not act does not have any inner knowledge.
