The scholars differed regarding raising the hands in prayer, I mean in its ruling, in the places in which it is raised, and in the limit of raising it in it, and where it ends. As for the ruling, some say that raising the hands is a sunnah in prayer, and some say that it is obligatory, and these people are divided into categories. Some of them oblige that in the opening takbeer. Only some of them made it obligatory at the opening, when lowering to bowing, and when rising from bowing, and some of them made it obligatory in these two positions and when prostrating, and as for the positions in which the hands are raised in prayer.
