Description: Imam al-Sadiq (a.s.) said, ‘Allah does not accept any act without inner knowledge [i.e. awareness of what one is doing], and inner knowledge only comes through prior action. So whoever knows intrinsically, his knowledge will lead him to action, and whoever does not act does not have any inner knowledge.’
الإمامُ الصّادقُ (عَلَيهِ الّسَلامُ): لا يَقبَلُ اللّهُ عَمَلاً إلّا بِمَعرِفَةٍ، ولا مَعرِفَةً إلّا بِعَمَلٍ ، فمَن عَرَفَ دَلَّتهُ المَعرِفَةُ عَلَي العَمَلِ ، ومَن لَم يَعمَلْ فلا مَعرِفَةَ لَهُ .

Description: The Prophet (S) said, ‘The light of inner knowledge is brought about by hunger whereas distance from Allah is caused by satiety. Proximity to Allah is brought about by loving the poor and drawing near to them, so do not eat to your fill lest the light of inner knowledge be extinguished from your hearts.’
