The Qur'an orders as well as refrains, remains silent and also speaks. It is the proof of Allah before His creation. He has taken from them a pledge (to act) upon it. He has perfected its effulgence, and completed through it His religion. He let the Prophet leave this world when he had conveyed to the people all His commands of guidance through the Qur'an. 
You should therefore regard Allah great as he has held Himself great, because He has not concealed anything of His religion from you, nor has He left out anything which He likes or which He dislikes, but He made for it a clear emblem (of guidance) and a definite sign which either refrains from it or calls towards it. His pleasure is the same for all time to come.
You should know that He will not be pleased with you for anything for which He was displeased with those before you, and He will not be displeased with you for anything for which He was pleased with those before you. You are treading on a clear path, and are speaking the same as the people before you had spoken. Allah is enough for your needs in this world. He has persuaded you to remain thankful, and has made it obligatory on you to mention Him with your tongues.
He has advised you to exercise fear and has made it the highest point of His pleasure and all that He requires from His creatures. You should therefore fear Allah, who is such that you are as though just in front of Him, and your forelocks are in His grip, and your change of position is in His control. If you conceal a matter, He will know of it. If you disclose a matter, He will record it. For this He has appointed honoured guards (angels) who do not omit any rightful matter nor include anything incorrect. 
Therefore, hasten towards the place of return and go ahead of (your) deaths (by collecting provision for the next world). Shortly, the expectations of the people will be cut short and death will overtake them while the door of repentance will be closed for them. You are still in a place to which those who were before you have been wishing to return. In this world, which is not your house, you are just a traveller in motion. 
You have been given the call to leave from here, and you have been ordered to collect provision while you are here. You should know that this thin skin cannot tolerate the Fire (of Hell). So, have pity on yourselves because you have already tried it in the tribulations of the world.
Have you ever seen the crying of a person who has been pricked with a thorn or who bleeds due to stumbling or whom hot sand has burnt? How would he feel when he is between two frying pans of Hell with stones all round with Satan as his companion? Do you know that when Malik (the guard-in-charge of Hell) is angry with the fire, its parts begin to clash with each other (in rage), and, when he scolds it, it leaps between the doors of Hell crying on account of his scolding.
O you who are advanced in years, whom old age has made hoary, how will you feel when rings of fire will touch the bones of your neck, and handcuffs hold so hard that they eat away the flesh of the forearms? (Fear) Allah! Allah! O crowd of men, while you are in good health before sickness (grips you) and you are in ease before straitness (overtakes you). 
You should try for the release of your necks before their mortgage is foreclosed, keep your eyes awake at night, make your bellies lean, use your feet, spend your money, take your bodies and spend them over yourselves, and do not be niggardly about them, because Allah the Glorified, has said:
... if you help (in the way) of Allah, He will (also) help you, and will set firm your feet. (Qur'an, 47:7)
and He, the Sublime. has said:
Who is he who would loan unto Allah a goodly loan so that He may double it for him, and for him shall be a noble recompense. (Qur'an, 57:11)
He does not seek your support because of any weakness, nor does He demand a loan from you because of shortage. He seeks your help, although He possesses all ..the armies of the skies and the earth (48:7) and He is the All-mighty, the All-wise (14:4). He seeks a loan from you, although He owns ..the treasuries of the skies and the earth (63:7) and ..He is the All-sufficient, the All-laudable (22:64). (Rather) He intends to try you as to which of you is best in conduct (11:7). 
You should therefore be quick in performance of (good) acts so that you may be with His neighbours in His abode; He made His Prophet's companions of these neighbours and made the angels to visit them. He has honoured their ears so that the sound of Hell fire may never reach them, and He has afforded protection to their bodies from weariness and fatigue.
. . . that is the grace of Allah, He bestoweth it upon whomsoever He willeth; and Allah is the Lord of Mighty Grace. (Qur'an, 57:21)
I say what you are hearing. I seek Allah's help for myself and yourselves. He is enough for us and He is ..an excellent trustee (3:173).
