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 Qur’an) silently. Some scholars, may Allah 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 Allah” (I seek forgiveness of Allah) 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 Qur’an.
4- In one minute, you can memorize a small verse of the Qur’an.
5- In one minute, you can say ”Laa ilaaha illa Allah wahdahu laa shareeka lah, lahul mulku wa lahul hamdu wa huwa ‘ala kulli shay’in qadeer” (None has the right to be worshiped except Allah 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 Allah from the children of Ismaa’eel (Ishmael), may Allah exalt his mention.
6- In one minute, you can say ”Subhaana Allah wa bihamdihi” (How perfect Allah 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 Allah wa bihamdihi, Subhaana Allah Al-Azeem” (How perfect Allah is and all praise be to Him, how perfect Allah 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 Allah. [ [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 Allah, wal hamdu lillaah, wa laa ilaaha illa Allah, wallaahu Akbar” (How perfect Allah is, all praise be to Allah, None has the right to be worshipped except Allah, and Allah 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 Allah, and the best of all speeches, and their weight on the scale of good deeds is very heavy, as reported in authentic narrations.
9- In one minute, you can say ”la hawla wa laa quwwata illa billaah” (there is neither might nor power except by Allah) more than 40 times. This is a treasure among the treasures of Paradise, as reported by Al-Bukhaari and Muslim, may Allah have mercy upon them. It is also one of the major reasons of bearing difficulties and hardship.
10- In one minute, you can say ”Laa ilaaha illa Allah” (None has the right to be worshiped but Allah) approximately 50 times, and it is the greatest word, as it is the word of Tawheed (Oneness of Allah), a good word, and a firm statement, and whoever says this expression as his last words before breathing his last, he will enter Paradise; the above expression also has other virtues.
11- In one minute, you can say: ”Subhaanah Allah wa bihamdihi, ‘adada khalqihi, wa ridha nafsihi, wa zinata ‘arshihi, wa midaada kalimaatihi” (How perfect Allah is and all praise be to Allah, by the number of His Creation and His Pleasure, and by the weight of His Throne, and the ink of His Words) more than 15 times. This statement equals multiplied rewards of ordinary legislated mention of Allah, as confirmed by the Prophet, sallallaahu ‘alayhi wa sallam.
13- In one minute, you can give a short summarized speech which could be very beneficial for the listeners.
14- In one minute, you can exalt the mention of the Prophet, sallallaahu ‘alayhi wa sallam, by saying ”Sala Allahu ‘Alayhi wa sallam” (may Allah exalt his mention) 50 times, for which Allah will exalt your mention 500 times, because one exaltation is multiplied tenfold.
15- In one minute, you can think about the creation of the heavens and the earth, as a result you will be considered among the people of understanding whom Allah mentioned in the Qur’an.
16- In one minute, you can think about being grateful to Allah, loving Him, fearing Him, hoping for Him (His Mercy) and longing to meet Him; by doing so, you would have achieved great acts of worship while you may be lying down on your bed or walking in the street.
17- In one minute, you can read more than two pages from a beneficial book which is easy to understand.
18- In one minute, you can keep ties with your kinship by phoning them.
19- In one minute, you can supplicate with general supplications.
20- In one minute, you can greet (by saying Salaam to) a number of people and shake hands with them.
21- In one minute, you can forbid evil.
22- In one minute, you can enjoin good.
23- In one minute, you can advise a brother.
24- In one minute, you can intercede in doing good for a person.
25- In one minute, you can comfort a distressed person.
26- In one minute, you can take off an obstacle from the road.
27- By benefiting from one minute, you will preserve and benefit from other times.
Therefore, according to your sincerity and being conscious that Allah is always watching you, your good deeds and reward may be multiplied.
You should know that most of the actions do not necessitate anything from you, you do not need to be in a state of purity and they do not cause you any hardship.
You may do the above deeds while walking on the road, or being in a car, or while lying down, or sitting, or waiting for someone. In addition to this, these actions are the best reasons for achieving happiness, being content and overcoming problems and difficulties.
Finally, I suggest that you keep this paper in your pocket in order to remember these actions and to read it over to your Muslim brothers. By doing so, you will help them to benefit from their time and you should not underestimate any good deed. Indeed the person who enjoins others to do good is as if he did those good actions himself [he will get their reward without diminishing anything from their own reward].
