PLACE OF GATHERING
Then the angels will assemble all of them naked, uncircumcised and barefooted to the place of Hashr. (Place of Gathering)
Those  who pervert the Truth in Our Signs are not hidden from Us. Which is  better? -he that is cast into the Fire, or he that comes safe through,  on the Day of Judgment? Do what ye will: Verily He seeth (clearly) all  that ye do.
Surah Ha-miim, 41:40
And listen for the Day when the  Caller will call out from a place quite near, -The Day when they will  hear a (mighty) Blast in (very) truth: that will be the day of  Ressurection.
Verily it is We Who give Life and Death; and to Us is  the Final Goal-- The Day when the Earth will be rent asunder, from (men)  hurrying out : that will be a gathering together,--quite easy for  Us.
Surah Qaf, 50:41-44
PEOPLE WILL BE GATHERED WITH WHOM THEY LOVED
On  the authority of Jabir (R.A), "Every soul shall be gathered according  to its desire. So, whoever loved disbelief will be with the  disbelievers, and his deeds will not benefits him at all."
[Narrated by  Tabarani]
A man asked the Prophet (S.A.W.), When is the Hour (of Judgment)?
The Prophet (S.A.W.), asked him "What have you prepared for it?"
He replied, "Nothing, except that I love Allah (S.W.T.) and His Messengers."
The Prophet (S.A.W.) told him, "You are with those whom you love."
[Narrated by Al-Bukhari and Muslim]
