Why will there be one woman in Paradise out of ninety-nine women, with the rest of them in the Fire, as stated in the Hadith narrated by Ibn Abbas?

The hadith in question has not been authentically reported from the Prophet (peace be upon him). Abu Ya'la narrated it with the wording: "Out of ninety-nine women, one is in Paradise, and the rest are in the Fire. This greatly distressed those among the Muhajiroon who were present with the Messenger of Allah (peace be upon him). So the Messenger of Allah (peace be upon him) said: 'When a Muslim woman becomes pregnant, she receives the reward of one who stands (in prayer), fasts, performs Hajj, and strives in the path of Allah. When she gives birth, for the first suckle she gives (her child), she receives the reward of giving life to a soul.'"

Al-Albani explained in "Silsilah al-Da'ifah" that its chain of narration is very weak due to Al-Husayn ibn Qays al-Rahbi (Hanash), whom Ahmad, Al-Nasa'i, and others described as "abandoned in hadith." Al-Bukhari said of him: "His hadith are very objectionable, and his hadith should not be written down." Shaykh Husayn Salim Asad also weakened its chain of narration in his verification of Musnad Abu Ya'la.
