The Gatherer, The One who gathers the creatures on a day that there is no doubt about, that is the Day of Judgment.
Allah is Al-Jami’, He is The One who has power to assemble and arrange all that which has been dispersed. He is the one who composes and connects things together.
Our Lord, surely You will gather the people for a Day about which there is no doubt. Indeed, Allah does not fail in His promise.” (Quran 3:9)
Does man think that We will not assemble his bones? Yes. [We are] Able [even] to proportion his fingertips. But man, desires to continue in sin. (Quran 75:3-5)
This is the Day of Judgement; We will have assembled you and the former peoples. (Quran 77:38)
And those who believed and whose descendants followed them in faith – We will join with them their descendants, and We will not deprive them of anything of their deeds. Every person, for what he earned, is retained. (Quran 52:21)
