Then, through two short and extremely meaningful sentences, it characterizes the Blessed, thus: And as for him who feared his Lord's presence and restrained the soul from the low desires. Then surely the Garden will be the Abode. Yes, the first condition of being 'blessed' is 'fear' caused by 'knowledge' knowing the presence of the Lord and being afraid of disobeying His command.
The second condition, which is, indeed, the fruit of knowledge and fear of Allah, is restraining the soul from rebellion, since, all the sins, corruptions and disasters, come from low desires which is the worst god worshipped in the world. The means of Satan to influence in Man's entity, is still 'low desire'. It is this inner evil that opens the gate for the outer Evil to come in, or else this case would never be possible, as Sura Al-Hijr, No.
15 verse 42 says: For over My servants no authority shalt thou have, except such as pat themselves in the wrong and follow thee. Explanations: What is the meaning of the Presence of the Lord? It is worthy to note that in Verse 40, of the current Sura, it says: ...as for him who feared his Lord's presence... but it does not say: 'as for (1) Nur-uth-Thaqalayn, vol.5, p.506, Tradition No.43. him who feared his Lord'. Then, what is 'the 'Lord's presence'?
The following are some different commentaries to be considered: It means 'the halting-places in the Hereafter' wherein Man stands in front of the Lord for Judgment.Therefore, 'the Lord's presence' is in the sense of 'his presence with his Lord', i.e. the standing of Man before his Lord. It points to 'Allah's knowledge and His protection' for all human beings; as Sura Rad No. 11, verse 33 says: Is then He Who standeth over every soul (and knoweth) all that it doth, (like any others) ?
The next evidence to this commentary is the tradition that has been narrated from Imam Sadiq who said: He who knows that Allah sees him, hears what he says, knows what he does regarding good or evil, and this consciousness keeps him away from doing wrong, it is he who '...feared his Lord's presence and restrained the soul from the low desires'. It means 'His Justice' since, His Holy Essence is not frightening. The fear is for His Justice.
In fact, this fear is obtained from the comparison between our actions and His Justice. Criminals tremble when they see the just judge, and fear when they hear the words 'court and Judgment', while an innocent person feels no fear of any of them.
