Allah, the Exalted, says:
"So hasten towards all that is good". (2:148)
"And march forth in the way (which leads to) forgiveness from your Rubb, and for Jannah as wide as are the heavens and the earth, prepared for Al-Muttaqun (the pious)". (3:133)
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "Be prompt in doing good deeds (before you are overtaken) by turbulence which would be like a part of the dark night. A man would be a believer in the morning and turn to disbelief in the evening, or he would be a believer in the evening and turn disbeliever in the morning, and would sell his Faith for worldly goods.'' [Muslim].
Commentary: This Hadith tells that the Day of Resurrection will be preceded by a long chain of calamities. Because of the rush of these calamities, religion and Faith will loose their value in people. There will be a race for wealth, so much so that people would not hesitate to compromise their religion and Faith to acquire wealth. People will rapidly change their faces. This is what actually happening. In this situation true believers are exhorted to adhere strictly to Faith and perform noble deeds without delay.
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "Hasten to do good deeds before you are overtaken by one of the seven afflictions.'' Then (giving a warning) he said, "Are you waiting for such poverty which will make you unmindful of devotion; or prosperity which will make you corrupt, or disease as will disable you, or such senility as will make you mentally unstable, or sudden death, or Ad-Dajjal who is the worst expected absent, or the Hour, and the Hour will be most grievous and most bitter". [At-Tirmidhi].
Commentary: The purpose of this Hadith is that before overcoming of the obstructions, one should do one's best to improve his Hereafter by means of good deeds lest one is deprived of good deeds by some obstruction.
