What is the validity of interpreting the verse: "So eat it with wholesome ease" as meaning that the wife's money can cure the husband?

Allah Almighty says: {And give women their bridal gifts graciously. But if they give up willingly to you anything of it, then take it and enjoy it with good cheer} [An-Nisa: 4].

This verse is evidence that a woman has the right to dispose of her property by donation if she is of sound mind, and that her guardian has no claim to any part of the bridal gift except what she willingly gives.

As for what was narrated from Ali (may Allah be pleased with him): "If any of you complains of something, let him ask his wife for three dirhams from her bridal gift, then let him buy honey with it and drink it with rainwater. Thus, Allah combines the wholesome and palatable, the blessed water, and the cure," its chain of narration is weak.

It is not permissible to say that healing is in the hands of Allah and then your wife; because all healing is in the hands of Allah alone, as the Prophet (peace and blessings be upon him) said: "O Allah, Lord of mankind, Remover of hardship, heal, for You are the Healer, there is no healer but You, a healing that leaves no sickness."
