"and cover not the truth with falsehood nor conceal the truth when you know (what it is)... nay seek (Allah's) help with patient perseverance and prayer: it is indeed hard except to those who bring a lowly spirit. who bear in mind the certainty that they are to meet their lord and that they are to return to him."(Q2[Baqarah]:42-46)
The saying of the Exalted, "and cover not Truth. with falsehood": The truth, which the children of Israel covered with falsehood, was their faith in some of what the Torah contained. The falsehood by which they covered truth was their disbelief and rejection of some of what the Torah contained such as the descriptions of the Messenger of Allah (salal/ahu alayhi wa sal/am) and other things. This is explained in His saying:
"so do you believe in some of the Book and disbelieve in the rest?" (Q2[Baqarah]:85)
And consideration is given to the generality of the wording, not to the specific occurrence that resulted in the revelation of the verse as has preceded.
The saying of the Exalted:
"Nay seek (Allah's) help with patient perseverance and prayer"
As for having patience upon the matters of this world and the Hereafter then there is no obscurity in this, but as for the result of having patience in prayer then this is pointed out by Allah in a number of verses of His Book. So He mentioned that from amongst the results of this is that the one who prays is prevented from actions that are not, befitting, this in His saying:
"indeed prayer prevents from immoral and evil deeds" (Q2 9[Al-Ankabut]:45).
And that from the results of this is that it brings about increase in provisions, this in His saying:
"and enjoin prayer on your family, and be patient in offering them. We ask not of you any provision, rather We give it to you. And the goodly ends for those that fear Allah." (Q20[Ta Ha]:132)
This is why when a matter concerned the Messenger of Allah (salallahu alayhi wa sallam) he would resort to prayer.
This is further clarified when we understand that when the servant stands before his Lord, discoursing with Him, reciting His Book, then all of the matters of this world become insignificant to him in the face of his desire for what is with Allah, and his dislike of not attaining it. So, as a result, he distances himself from all that Allah is not pleased with, and hence Allah provides for him and guides him.
The saying of the Exalted:
" Who bear in mind the certainty (yadhunnoon) that they are to meet their Lord and that they are to return to Him.": The meaning of dhann here is certainty as is proven by His words, "And they have certainty in the Hereafter" (Q2[Baqarah]:4)
"And those that give (in charity) what they give, with their hearts full of fear, because they are certain that they shall return to their Lord." (Q23 [A1-Muminun]:60)
