If I ask you how many Muslims are there on earth right now? 1.3 billion, 1.4 billion Muslims? Who wants rewards for every believing man and believing woman on the earth?
A Dua to Say
These are the words of the Prophet Muhammad (peace be upon him), not my words. And this comes from a hadith narrated by At-Tabarani that has a good chain.
The Prophet Muhammad (peace be upon him) said that if we do the next action, we will get the reward for every believing servant, male and female, that is alive (he could have meant the people who are dead also).
Whosoever will seek forgiveness for the believing men and the believing women, Allah will give them, for every believing man and believing woman one good deed.
Allahu Akbar!
So I want you to do one thing right now. I want you to say this dua with me:
“O Allah! Forgive the believing men and believing women.”
If you want to add on, the scholars have said that you say this particular dua from the Quran and you will get all of it:
Our Lord, forgive us and our brothers who preceded us in faith and put not in our hearts [any] resentment toward those who have believed. Our Lord, indeed You are Kind and Merciful. (Quran 59: 10)
