The night and the day: (S, K:) so called because of the assembling [of people therein]; like as they are called اِبْنَا سَمِيرٍ because people held conversation therein: (S:) or the two nights during which the moon becomes concealed by its proximity to the sun. (TA.) And اِبْنُ جَمِيرٍ, (IAar, S,) or
اِبْنُ جُمَيْرٍ, (Lh, Th,) The moon in the night when it is concealed by its proximity to the sun: (TA:) or the moon in the end of the [lunar] month; because the sun conceals it (تَجْمُرُهُ, i. e. تُوَارِيهِ): (IAar, TA:) or the dark night: (S:) or the night in which the moon does not rise, either in the first part thereof or in the last: (TA:) or the last night of the [lunar] month. (Aboo-'Amr Ez-Záhid, TA.) You say,
جَاءَنَا فَحْمَةَ ابْنُ جُمَيْرٍ [He came to us in the darkest part of the moonless night, or of the night in which the moon did not rise]. (Th, TA.) And
لَا أَفْعَلُ ذٰلِكَ مَا جَمَرَ ابْنُ جُمَيْرٍ [I will not do that as long as the moon in the end of the lunar month becomes concealed by its proximity to the sun; i. e., I will never do it]. (Lh, TA.)
