بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيْمِ
Verily those who believe and work righteous works — these! they are the best of created beings. Their reward with their Lord will be Gardens of Eden, as a residence, underneath which rivers flow, wherein they shall abide forever. Allah is pleased with them, because of [their] obedience of Him, and they are pleased with Him, because of His reward. That is [the reward] for him who fears his Lord, [for him] who fears His punishment and hence desists from disobeying Him, exalted be He.
=====================================================
His words, Exalted is He:
…This is [the reward] for him who fears his Lord.
He said:
Fear (khashiya) is [experienced] privately, within [lit. is secret, sirr], whereas humble submission (khushū‘) is shown openly (‘alāniyya). As for the one whose bodily members are in a state of humble submission, Satan will not approach him.
He was asked, ‘What is humble submission (khushū‘)?’ He replied:
It is standing before Allah and being steadfast (ṣabr) in that.
He [continued]:
The perfection of fear [of Allah] (khashiya) is the abandonment of sins, both [those that are committed] in secret and openly
