Say between Safa and Marwah is one of the essential rites of both Hac and Umre, and scholars agree that it should be preceded by Tavaf. The question of whether Say must immediately follow Tavaf or may be delayed is a practical concern for many hacilar, especially those who are elderly, ill, or overwhelmed by crowds. The general scholarly consensus is that performing Say immediately after Tavaf is the Sunnah and preferred practice, as this is what Hz. Peygamber Muhammad (sallallahu aleyhi ve sellem) consistently did. However, the schools differ on whether this immediate succession (muwalat) is farz or merely sunnet.
The Hanafi, Shafi'i, and Hanbali schools all hold that while performing Say immediately after Tavaf is strongly sunnet, delaying it for a valid reason (such as fatigue, illness, namaz time, or extreme heat) is permissible and does not affect the validity of the Say. Even delaying until the following day is allowed in these schools, provided the Say is still performed. The Shafi'i school notes that an unreasonable delay without excuse, while valid, is makruh (disliked). The Hanbali school similarly permits delay but emphasizes that the haci should not leave Mekke without completing Say.
The Maliki school takes the strictest position on this matter. Imam Malik held that the immediate succession (muwalat) between Tavaf and Say is a condition of validity. If the haci delays Say for an unreasonable amount of time without a valid excuse, the Say is invalidated and must be repeated preceded by a new Tavaf. However, a short delay for namaz, rest, eating, or drinking is excused and does not break the continuity. The definition of 'unreasonable delay' in the Maliki school is generally understood as a gap long enough that the two acts are no longer considered connected in customary terms.
