Is it permissible for a man who is able to attend congregational prayer to delay his prayer so that he may pray in congregation with someone who arrives late after its conclusion, in order not to diminish the reward of the latecomer?

A Muslim should first prioritize their worship and perfect it, then strive to perfect others, in accordance with the Almighty's saying in Surat Al-Asr. For Allah Almighty mentioned that those who are saved from loss are those who perfected themselves through faith and righteous deeds, then strove to perfect others by enjoining truth and patience. Accordingly, a Muslim is commanded to attend the first congregational prayer in the mosque, which is the one concerning which narrations have been reported regarding its virtue and reward. It is not correct to say that the reward of twenty-seven degrees also applies to the second congregation. For praying in the second congregation is better than praying alone, but it does not reach the reward of the first congregation. If a Muslim is keen for someone who missed the first prayer to attain the reward of the congregation, they can return and pray with them again. By doing so, they would have done good to them and given charity to them, without forfeiting the reward and virtue of the first congregation, as the Messenger of Allah, peace and blessings be upon him, did when he said: "Who will give charity to this one by praying with him?" So, let a Muslim beware of Satan beautifying for them the turning away from the virtuous act of worship they were commanded to perform, and preferring a less virtuous matter.
