The Hadith: 'Anyone who prays forty consecutive Salahs in my Masjid...'

Q 1: The Messenger of Allah (peace be upon him) said, “Anyone who prays forty Salahs (Prayers) in my Masjid (mosque) without missing any of the obligatory Salahs will have all their past sins forgiven by Allah.” 2. The Messenger of Allah (peace be upon him) said, “Anyone who prays forty days in my Masjid without missing any of the obligatory Salahs will be as released from their sins as when their mother gave birth to them.” Are the texts of these two Hadith Sahih (authentic)?

A: The Hadith are Da‘if (weak) and Mudtarib (a Hadith with disagreement over a transmitter or the text) due to disagreement in the Matn (texts of the Hadith) and Sanad (chains of narrators).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
