Is the reason for suitors' rejection of a veiled woman a flaw in her, or in her commitment and veil?

All matters are in the hands of Allah the Almighty. He distributes provisions among His servants as He wills, for He is the All-Knowing, the All-Aware. All good for the servant lies in contentment. The failure to complete a marriage after suitors have come forward may be a trial by which Allah raises one's ranks. The mother's stance, linking the lack of marriage to the niqab, is incorrect. Allah the Almighty says: "And whoever fears Allah – He will make for him a way out." There is no need to worry about age, as you are still young. Beware of the whispers of Satan. You must turn to Allah the Almighty, make abundant supplication and entreaty to Him, utilize virtuous times, especially prayer in the depth of the night, and avoid gatherings with those who increase your worries.
