that the Messenger, blessings and peace be upon him, instructed that the sermon be awaited (1).
His statement, “It is disliked during their two nights,” means the nights of the two days of Tashriq. However, the author holds that the days of slaughter are two; hence he used the dual form, “during their two nights”—that is, the night of the eleventh and the night of the twelfth. This is because the Messenger, blessings and peace be upon him, said: “All the days of Tashriq are days for slaughter” (2). He also said: “The days of Tashriq are days of eating, drinking, and the remembrance of Allah” (3). This indicates that the proper time for slaughter is the daytime. Accordingly, slaughter at night is disliked, because the miserly may choose to slaughter at night so that they will not have to give charity; for this reason, it is deemed disliked.
It has also been said that the reason for its being disliked is to avoid scholarly disagreement—that is, the disagreement of those scholars who hold that slaughter at night is invalid, since Allah the Exalted says: “and mention the name of Allah on appointed days” [al-Hajj 22:28]. The response to this argument is that the Arabs use the term “days” to include nights; thus, they may say “days” while including the nights. They also use the term “nights” while intending both night and day, as in His saying: “They shall wait by themselves for four months and ten [days]” [al-Baqarah 2:234]—that is, ten nights, with both the nights and days intended. The argument from scholarly disagreement is itself disputed, and the correct view is that it is not a valid basis for legal reasoning.
