On any day when Hallel was recited there was no Ma`amad [service] at shaharith; [on the day when] a Musaf-offering [was brought] there was none. At Ne`ilah, [on the day observed as] the wood-festival there was none at Minhah; this is the opinion of R. Akiba [T3]. Ben `Azzai said to him: thus did R. Joshua [T2] learn: [on the day when] a Musaf-offering [was brought] there was none at Minhah; [on the day observed as] the wood-festival there was none at the closing of the gates. Thereupon R. Akiba [T3] retracted and learnt like ben `Azzai.
