Will marrying a repentant fornicatress and concealing her past bring reward from Allah in the Hereafter?

If a woman who committed Zina repents, it is permissible to marry her after ensuring her womb is clear. And whoever marries her with the intention of covering her (faults) will receive a great reward, because whoever covers a Muslim, Allah will cover him in this world and the Hereafter. And whoever seeks out the faults of Muslims, Allah will seek out his faults and expose him. This is indicated by the grave danger of exposure in this world and the Hereafter, as mentioned in the Hadith (definition): "O assembly of those who have submitted with their tongues but faith has not reached their hearts! Do not harm Muslims, nor shame them, nor seek out their faults. For indeed, whoever seeks out the fault of his Muslim brother, Allah will seek out his fault. And whoever Allah seeks out his fault, He will expose him, even if he is in the privacy of his home." In the Hereafter, the matter will be even greater, for whoever unlawfully takes something in this world will come on the Day of Resurrection carrying it on his back, increasing his exposure.
