As to Allah's saying...
As to Allah's saying: “ Has not the time yet come for those who believe that their hearts should be submissive when remembering Allah and what has come down of the truth,” [^5] it may be that it is the formal faith the very belief in what the Prophet ( s ) has brought which is intended here, for the true faith is accompanied by a degree of submission; or the submission in the noble āyah may refer to a submission at its complete degree, as sometimes they apply the word, ‛ ālim (erudite) to the one whose knowledge has reached the limit of faith.
In the noble āyah : “… verily only the erudite among Allah's servants fear Him,” [^6] The reference may be to them. In the terms of the Book and the Sunnah , knowledge, faith and Islam refer to different degrees, the explanation of which is out of the scope of these papers.
Generally speaking, the sālik on the way to the Hereafter specially if with the mi‛rāj (ascending) step of the Salat will have to make his heart submissive by the light of knowledge and faith, so as to strengthen, as much as he can, this divine gift and the beneficent gleam, in his heart, trying to keep this state during the whole length of the Salat .
This state of consolidation and stability, though a bit difficult at the beginning for people like us, it becomes quite possible by practice and by exercising the heart. My dear, acquiring perfection and the provision for the Hereafter requires demand and seriousness, and the greater the demand, the more it deserves being serious about it.
Certainly, with such a state of weakness, laxity and carelessness, one cannot ascend to the divine proximity and to be in a place neighboring the Lord of Might. One has to manly set forth in order to reach what one wants.
Since you do believe in the Hereafter, and find no way of comparability between that world and this whether regarding their happiness and perfection, or their sufferings and calamities, as that world is eternal, with no death and perishing, where the happy live in comfort and dignity and in everlasting bliss, a comfort which has no like in this world, a divine glory and sovereignty, the like of which cannot be found in this life, and a bliss which never occurs in anybody's imagination, and similarly regarding the sufferings of that world, its pains, torments and evils can have no match in this world you should know that the way to happiness runs through obeying Allah, the Lord of Might.
