How Much Time Should a Husband Spend With His Wife in Islam?

No, you are not sinful  as long as you are fulfilling her basic rights and not neglecting her.

In Islam, a husband must provide financial support, good treatment, and reasonable companionship. If you are sincerely trying and giving 30–60 minutes of quality time daily despite being busy, this is not a sin.

وَعَاشِرُوهُنَّ بِالْمَعْرُوفِ

Live with them in kindness.

(Qur’an 4:19)

The Prophet ﷺ said:

خَيْرُكُمْ خَيْرُكُمْ لِأَهْلِهِ، وَأَنَا خَيْرُكُمْ لِأَهْلِي

The best of you are the best to their families, and I am the best to my family.

 (Sunan al-Tirmizi)

So if you are not being harsh or careless, but only limited due to responsibilities, you are not sinful.

The best approach is for both of you to sit together and clearly discuss your expectations. Marriage is not a competition; it is a partnership.

May Allah put love, mercy, and understanding between you both, and bless your marriage with peace and barakah.
