Translation of the verse 4 from Surah Nuh : Number of verses 28 - - page 570 - Part 29.
"He (Allah) will forgive you of your sins and respite you to an appointed term. Verily, the term of Allah when it comes, cannot be delayed, if you but knew."
Allah will forgive you of your sins and delay you for a specified term. Indeed, the time [set by] Allah, when it comes, will not be delayed, if you only knew.' "
(71:4) He will forgive your sins *3 and will grant you respite until an appointed term. *4 Indeed when Allah's appointed term comes, it cannot be deferred; *5 if you only knew!' *6
*3) The sentence yaghfir la-kum min dhunub-i-kum in the original does not mean that Allah will forgive some of their sins, but its correct meaning is: "If you accept and acknowledge the three things which are being presented before you, He will forgive all the sins that you have committed in the past."
*4) That is, "If you accepted these three things, you would be given respite to live in the world until the time that Allah has appointed for your natural death."
*5) "The appointed time of Allah .. ": the time fixed by Allah for sending down a torment on a people. In this regard the Qur'an has at several places stated explicitly that when Allah's torment has been decreed for a certain people, they are not pardoned even if they affirm the faith after it.
*6) That is, "If you come to know fully well that the time which is now passing after you have received Allah's message through me, is, in fact, a period of respite that has been granted to you for affirming the faith-and there is no chance of escape from Allah's torment after the term of respite has elapsed-you would testify to the faith without delay and would not like to postpone it until the torment actually started descending on you."
