And the believing men and believing women are patrons of one another, they enjoin what is right and forbid what is wrong and establish prayer and pay welfare-tax and obey Lord Allah and His Messenger; for such men will have Mercy of Allah upon them, indeed, Allah is the Exalted, the Wise.
During the revelation of this verse, Adhikr—Wise Reminder as told in verse 3: 58—was not formed. But today, Adhikr is formed as a Book. So, without It, nobody can become a believer as explained in verses 2: 177; 3: 97 and 187. The Trust Adhikr is revealed to accept the repentance of believing men and women as told in verse 33: 73. Believing men and women are patrons to one another. They are testifying and following Adhikr—the Best Book so that they will not have any evil feelings towards another. Even if they got a chance to do something evil, either of them will remind the other with Adhikr which is the Food, Cloth, and Sight of the human soul as explained in verse 7: 26. Such are brothers and sisters to each other as explained in verses 8: 73-74. They can dine together irrespective of relationship and gender as told in verse 24: 61. The believer’s character and behavior will be just opposite to the hypocritical men and women as explained in verses 9: 67-68. If hypocrites are eager in getting welfare-tax, believing men and women are wishing to give it. The believing men and women will protect and help each other, they are belonging to the Lord’s party whereas the hypocrites and their blind followers are belonging to Satan’s party as explained in verses 4: 150-151.
As there is no group of believers anywhere in the world, there is no group prayer. The odd believer's lifestyle should be as explained in verses 7: 205-206 and 22: 77-78. The believing man and woman will select Asia (women of Pharaoh) and Maryam (mother of Jesus) as the role models as explained in verse 2: 221. See explanations 2: 2-5; 3: 42-43 and 101-102.
