Is the Hadith, "Whoever abandons the Asr prayer will have no fruit in his offspring," authentic, and if so, what is its full text?

To proceed:

Istihada (non-menstrual vaginal bleeding) is blood from a vein that flows outside of the regular menstruation period. It does not prohibit prayer, fasting, or sexual intercourse, unlike menstrual blood, which prohibits all of these.

A woman experiencing istihada must perform ablution (wudu) for each prayer when its time enters, and then she may pray as many obligatory and supererogatory prayers as she wishes with that ablution. Any blood that exits from her does not harm her. If she performs ablution before the prayer time or if nothing exits after her ablution, she is not required to perform ablution again.
