When are souls created according to Islam?

**Does Islam teach that souls are eternal to the past? And if so, where is this teaching found?** In other words, are souls "pre-eternal" (a term found [here](https://ijwr.ut.ac.ir/article_54600_77e74aa55a96f6f66183458935b59ff6.pdf)) or "past-complete" (a term found [here](https://arxiv.org/pdf/gr-qc/0110012.pdf)) , both terms just meaning that the soul has always existed, being past-eternal, aka eternal to the past, aka eternal with respective to the past. I understand that typically Islam teaches the pre-existence of souls from multiple sources (such as this [Shabir Ally video here](https://www.youtube.com/watch?v=6H6GBssaNiw) that actually seems to deny the pre-existence of souls or even possibly the existence of a soul), and **[Wikipedia](https://en.wikipedia.org/wiki/Pre-existence#Islam) specifically says that Islam teaches that souls were created at the same time that God created Adam. Is this true? If so, where is this teaching found?** I am not asking if souls exist, if souls exist eternally with respect to the future aka [never die](https://islam.stackexchange.com/questions/30733/does-the-soul-ever-die) , or about [mind-body dualism](https://en.wikipedia.org/wiki/Mind%E2%80%93body_dualism) .
