3042 There were various Arab superstitions and fancies which are combated and rejected here. (1) The blind, or the halt, or those afflicted with serious disease were supposed to be objects of divine displeasure, and as such not fit to be associated with us in meals in our houses: we are not to entertain such a thought, as we are not judges of the causes of people's misfortunes, which deserve our sympathy and kindness. (2) It was considered unbecoming to take meals in the houses of near relatives: this taboo is not approved. (3) A simple superstition about houses in our possession but not in our actual occupation is disapproved. (4) If people think they should not fall under obligation to casual friends, that does not apply to a sincere friend, in whose company a meal is not to be rejected, but welcomed. (5) If people make a superstition either that they should always eat separately, or that they must always eat in company, as some people weary of their own company think, either of them is wrong. Man is free and should regulate his life according to needs and circumstances. (R).
3043 The shades of meaning in Salam are explained in n. 2512 to 19:62. Here, we were first told that we might accept hospitality and good fellowship in each odier's houses. Now we are told what spirit should animate us in doing so. It should not be a spirit only of self-satisfaction in a worldly sense. It should rather be a spirit of good will in the highest spiritual sense of the term-purity of motives and purity of life, as in the sight of Allah. Cf. Dante in the Paradiso (iii. 85): "In His will is our Peace."

17 There is no blame on any of the three if they do not march forth in Allah’s cause. Moreover, some Muslims would give the keys of their homes to one of those who could not march forth (namely the blind, the disabled, or the sick) or their own relatives and ask them to enter their houses and eat at will but these people were shy to do that.
