Facing One Another In the Jannah

S 15:47 And we have deprived of what is in the chests of rancour, brothers facing one another on beds.

S 37:44 On beds facing one another.

S 56:16 Reclining thereon facing one another.

Now, if millions of people are supposed to make it to the Jannah, how might they all be on beds facing one another?

The verses suggest that only a small number would be up there. Allah's boss said that only one sect in 73 would make it but it seems that only very few in this sect would be 'the successful'.

From my post The Jannah-Bound

It was narrated from ‘Awf bin Malik that the Messenger of Allah(ﷺ) said:

“The Jews split into seventy-one sects, one of which will be in Paradise and seventy in Hell. The Christians split into seventy-two sects, seventy-one of which will be in Hell and one in Paradise. I swear by the One Whose Hand is the soul of Muhammad, my nation will split into seventy-three sects, one of which will be in Paradise and seventy-two in Hell.” It was said: “O Messenger of Allah, who are they?” He said: “The main body.”

According to the hadith above, the Jews have a 1/71 chance of getting into the Jannah, the Christians a 1/72 and the Muslims a 1/73 chance. The Jews and Christians have a greater chance of getting in, and all without converting to Islam; the Muslims, however, have just one chance in 73 of getting into it, depending upon their being in the right sect. It would seem that someone asked just which exactly the winning sect of Islam was, and that the founder of Islam tried to fob him off with a non-answer, which the translator renders "The main body", the word being "Al-jama'ah", 'The group'.

End of quote. It rather looks like the denizens of the Jannah would be like those sitting in a circle at an AA meeting. Perhaps it will be more like a sex addicts' meeting.
