What is the ruling on one who deliberately delays the prayer until the imam bows?

Question : The questioner says: Honorable Shaykh, some of the brothers sit in the rows waiting for the imam to bow. When the imam bows, they hurry and bow with him without reciting al-Fatihah. What is the ruling on this prayer?

Answer : I say that the Messenger of Allah (peace and blessings be upon him) said: This hadith is general for the imam, the one praying behind him, and the one praying alone. If it is general, then reciting al-Fatihah is a pillar of the prayer for the one praying behind the imam, except if the one praying behind the imam enters the mosque and finds the imam already bowing.
Then he advances, says the takbir for entering the prayer, and bows with the imam. In this case, reciting al-Fatihah is dropped for him. Otherwise, he must recite it. As for those who sit and talk until the imam is about to finish his recitation, then they stand up and enter the prayer with him, I fear they are in great danger.
In reality, they are mistaken, lacking in thought and reason. Because we would say to them: If you do not have the desire to enter the prayer tonight, if not, what did we say?
The reality is that these brothers who sit and talk, if they do not have the desire to enter the prayer with the imam except at this time when al-Fatihah is missed, then leave entering with him. Because the prayer other than the obligatory one is voluntary. Whoever wishes enters, and whoever wishes does not enter. So these brothers have erred against themselves, and I fear that their first two rak'ahs have been missed because they did not recite al-Fatihah in them. Yes.
If he says he is tired, we say: Enter with the imam and sit. And if he wants to bow, stand up and bow with him. As for sitting outside the prayer and leaving the recitation of al-Fatihah, this is a mistake. Yes.
