The Qur'an explicitly states that martyrs will die in heaven, and most Muslims believe this.
"Those who leave their homes in the cause of Allah, and are then slain or die,- On them will Allah bestow verily a goodly Provision: Truly Allah is He Who bestows the best provision. Verily He will admit them to a place with which they shall be well pleased: for Allah is All-Knowing, Most Forbearing."
- Quran 22:58–59
The virgins part on the other hand is a lot more iffy. And Muslims generally believe it's not acceptable to kill a single innocent, since the Qur'an says so, so only a very small minority support suicide bombing like 9/11 (on the argument that since US citizens fund the military, they count as soldiers, not non-combatants).
Muslims themselves have claimed not fearing death to be a reason for past military success. For instance the quote "I have bought you men who love death as much as you love life" from one of the early Muslim generals https://en.m.wikipedia.org/wiki/Khalid_ibn_al-Walid . He said it to the Persians, whom the Muslim armies eventually defeated.
The issue is not whether these things are said, or even whether they are acted upon, but whether they are causally effective, and a number of war stories is insufficient to establish this.
