Piecing the clean days (laqt, talfiq), fiqh rulings

Laqt, in lexicon, is taking a thing up from the ground and gathering it; any scattering of ears of grain or dates is laqt. In law it is taking the clean days between two bloods and judging them pure, or taking the days of blood and judging them menses; this view is called talfiq, piecing. Sahb is giving the interval the rule of menses, the opposite ¹.

If the clean interval between two bloods is shorter than three days it is not a separation; if it is three days or more it counts, and then one looks at whether one blood can be made menses. Abu Yusuf narrates that an interval under fifteen days does not separate; Muhammad narrates a rule by the length of the bloods and gives a further view in his book on menses; the Hindiyya collection says many later jurists issued fatwas on Abu Yusuf's narration as the easier ^{1 2}.

The Malikis hold that the woman piecing counts only the days of blood, not the days of clean, and must wash on each cessation in the days of piecing ³. The Shafi'is have two views when the cessation comes before fifteen days: sahb, that the rule of menses extends over the clean days, and laqt, that the clean days are picked up and judged clean; the sounder is sahb ³. The Hanbalis hold that a woman washes and prays in a moment of clean, and intercourse is not disliked then ³.
