It is likewise permitted, according to the sounder of the two scholarly opinions, to perform prayers that are tied to a specific cause during these intervals—such as the funeral prayer (ṣalāt al-janāzah), the prayer of greeting the mosque (taḥiyyat al-masjid), and the eclipse prayer (ṣalāt al-kusūf). The textual evidence that singles them out limits the general prohibition, so the ban applies only to voluntary prayers that have no particular cause; one may not initiate such unprompted supererogatory prayers at these times.
It is also permissible to make up the Fajr sunnah after the obligatory Fajr prayer, and to make up the Zuhr sunnah after ʿAṣr—especially when Zuhr has been combined with ʿAṣr—for it is authentically reported that the Prophet made up the Zuhr sunnah after ʿAṣr.
