We should study our daily portion of Rambam during the day, seeking to complete it before nightfall. If, for some reason, you were unable to complete it during the day, you should do so during the evening—until midnight, or even until dawn of the following day.
Charity
Charity has the ability to elicit Divine assistance, as can be seen in our Sages’ praise for charity before prayer (Bava Basra 10a).
Preciousness of Daytime Offerings
This is comparable to the law concerning sacrificial offerings in the Beis Hamikdash. Although there is no sacrificial service during the night, nevertheless, as long as the sacrifices had been slaughtered and their blood brought to the Altar while it was still daylight, the kohanim are permitted to carry limbs and fats of the sacrifices onto the Altar for burning throughout the night hours. For the Biblical command to bring these parts extends all the way until the crack of dawn of the following day; it was only to discourage procrastination that may result in missing the Biblical deadline that the Sages instituted a midnight deadline. Nevertheless, the kohanim must at least attempt to offer everything during daylight hours, without resorting to the above clause, because any mitzvah that is performed in its designated time is considered more precious (see Hil. Ma’aseh HaKorbanos 4:2).
