The time is the life of a person and it should be preserved and spent properly. Therefore, a wise person is he who preserves his time and does not waste it in useless things and idle talk. Rather, one should spend his time in good endeavours and in performing righteous deeds which should please Allaah, the Exalted, and which should benefit people. Hence, in every minute of your life, you may do something which will increase your status (in the Hereafter) and bring happiness to your nation.
Therefore, if you are keen to achieve glory and bring happiness to your people, you should not waste your time in resting and playing.
Indeed, in one minute, one may do much good and obtain a great reward. One single minute could extend your life, increase your acts of obedience, your understanding, your memorization (of the Quran), and your good deeds. If you know how to spend one minute, it can be added to the book of your good deeds (on the Day of Judgement).3
"Beware of every hour and how it passes, and only spend it in the best possible way, do not neglect yourself, but render it accustomed to the noblest and best of actions, and send to your grave that which will please you when you arrive to it." [Imam Ibn Al-Jawzee]
The following are some investments which you can do in one minute:
1- In one minute, you can recite chapter Al-Faatihah (the opening chapter of the Quran) silently. Some scholars, may Allaah have mercy upon them, stated that a person gets more than 1400 good deeds for reciting it once. If one recites it 7 times, one gets 9800 good deeds in one minute.
2- In one minute, you can say ''Astaghfiru Allaah'' (I seek forgiveness of Allaah) more than 100 times. The virtue of seeking forgiveness is well-known, it is a reason of obtaining forgiveness, entering Paradise, having good provisions, increasing one's strength, repelling harm, having affairs facilitated, the descent of rain, and increasing in wealth and children.
3- In one minute, you can read a part of the Quran.
4- In one minute, you can memorize a small verse of the Quran.
5- In one minute, you can say ''Laa ilaaha illa Allaah wahdahu laa shareeka lah, lahul mulku wa lahul hamdu wa huwa 'ala kulli chay'in qadeer'' (None has the right to be worshipped except Allaah Alone, He has neither partners nor associates, to Him belongs sovereignty and praise and He is over all things wholly capable) 20 times; its reward is setting 8 slaves free for the sake of Allaah from the children of Ismaa'eel (Ishmael), may Allaah exalt his mention.
6- In one minute, you can say ''Subhaana Allaah wa bihamdihi'' (How perfect Allaah is and all praise be to Him) 100 times, and whoever says this, his sins will be forgiven even if they were like the foams of the sea.
7- In one minute, you can say ''Subhaana Allaah wa bihamdihi, Subhaana Allaah Al-Adheem'' (How perfect Allaah is and all praise be to Him, how perfect Allaah is, The Supreme) 50 times, and these are two expressions which are easy to say, but they are very heavy on the scale of good deeds, and they are beloved to Allaah. [ [Bukhari: Hadith No:673, V:8] and [Bukhari, B:9, V:93, Hadith 652]].
Prophet Muhammad (sallahu Alayhi Wa Sallam) said, "There are) two words which are dear to the Beneficent (Allah) and very light (easy) for the tongue (to say), but very heavy in weight in the balance. They are: Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim (Allah is free from imperfection and His is the praise)'.
8- The Prophet, sallallaahu 'alayhi wa sallam, said: ''If I were to say: ''Subhaana Allaah, wal hamdu lillaah, wa laa ilaaha illa Allaah, wallaahu Akbar'' (How perfect Allaah is, all praise be to Allaah, None has the right to be worshipped except Allaah, and Allaah is the greatest.) it is better for me than the whole world.'' [Muslim]. In one minute, you can say all the above words 18 times, and these words are the most beloved words to Allaah, and the best of all speeches, and their weight on the scale of good deeds is very heavy, as reported in authentic narrations.
