Translation:

5. It may be if he divorced you (all) that Allah will give him in exchange Consorts better than you who submit (their wills) who believe who are devout who turn to Allah in repentance who worship (in humility) who travel (for faith) and fast previously married or virgins.

Notes (Tafseer)

5536. From the case of two in verse 4, we now come to the case of all the Consorts generally, in verse 5. Cf. xxxiii. 28-30. Their duties and responsibilities were higher than those of other women, and therefore their failure would also be more serious. This is only hypothetical, in order to show us the virtues expected of them: faith and devotion, worship and service, readiness for travel or hijrat, whether they were young or old, new to married life or otherwise. From them again the more general application follows-to all women in Islam.

5537. Saihat: literally, those who travel. Here it means those who fast. Note that the spiritual virtues are named in the descending order: submitting their wills (Islam), faith and devotion, turning ever to worship and faith, and performing other rites, or perhaps being content with asceticism. And this applies to all women, maiden girls or women of mature experience who were widows or separated from previous husbands by divorce.
