How do I deal with my mother who only prays Fajr on time during Ramadan, despite her commitment to the other prayers?

Allah Almighty has designated a specific time for each prayer, and whoever delays it beyond its time without a legitimate excuse has committed a grave sin, for "Indeed, prayer has been decreed upon the believers a time-constrained ordinance." The Dawn (Fajr) prayer holds a special significance; it is a distinguishing mark between believers and hypocrites. The Prophet, peace and blessings be upon him, said: "Whoever prays the two cool prayers (Al-Bardayn) will enter Paradise," referring to the Dawn (Subh) and Asr prayers. He also said: "No one who prays before sunrise and before sunset will enter the Fire." Hypocrites delay prayers beyond their prescribed times and are lazy in performing them, as Allah Almighty says: "And they do not come to prayer except while they are lazy." Therefore, it is necessary to encourage the mother to perform the Fajr prayer on time with wisdom and gentleness, explaining the verses and hadiths that encourage performing prayers on time and warn against neglecting them, while observing the mother's rights and showing dutifulness to her.
