– yābis(an) (dry): from the verb yabisa, yabisu, yabasan—patterned like taʿiba. It denotes something that has lost its moisture and become dry. In the ḥadith the word yābis(an) functions as a ḥāl, an adverbial phrase describing the object.

Points derived from the ḥadith:
1 – The Prophet’s Sunnah is to suffice with rubbing the semen off if it is dry and to wash it if it is moist.
2 – Human semen is pure, for the Prophet’s limiting himself to scraping it rather than washing it proves its purity; likewise, the fact that he left it on his garment until it dried—even though his habit was to hasten in removing impurities—confirms the same.
3 – It is recommended to wash semen, whether wet or dry, for the sake of complete cleanliness, just as one washes mucus and other pure bodily secretions.
4 – There is no need to avoid such non-impure secretions; it is permissible for them to remain on the body, clothing, or elsewhere. This is inferred from the semen remaining on his garment until it dried.
5 – The Prophet’s manner shows how little he took from the fleeting life of this world: the garment in which he slept was the very garment in which he prayed and went out. This teaches the community not to exaggerate in worldly matters but to long for the immense reward and bounty that lie with Allah.
6 – A woman’s service to her husband, her care for the household, and her fulfillment of what is due to him according to customary practice are part of good marital conduct.
7 – Appearing in public with the ordinary traces of eating, drinking, or marital relations does not compromise the virtue of modesty.
8 – A righteous wife who wishes to endear herself to her husband does not disdain tasks such as removing dirt or secretions from his clothes or body, knowing the great weight of her husband’s right upon her.
