Is the aforementioned Hadith authentic, and why will a woman see her Lord in Paradise only on the days of Eid al-Fitr and Eid al-Adha, while a man will see Him more often than she?

The seeing of their Lord by believing women in Paradise, just like believing men, is established due to the generality of the sacred texts which include both men and women. The hadith that specifically mentions women seeing [their Lord] on Eid al-Fitr and Eid al-Nahr is weak. The greatest bliss for the people of Paradise is seeing Allah, and this includes everyone. Men go to the market of Paradise every Friday and increase in beauty and handsomeness, and their women also increase in beauty and handsomeness while in their homes, due to seeing Allah the Almighty.
