There is no fault in the blind , and there is no fault in the lame , and there is no fault in the sick , neither in yourselves , that you eat of your houses , or your fathers ' houses , or your mothers ' houses , or your brothers ' houses , or your sisters ' houses , or the houses of your uncles or your aunts paternal , or the houses of your uncles or your aunts maternal , or that whereof you own the keys , or of your friend ; there is no fault in you that you eat all together , or in groups separately . But when you enter houses , greet one another with a greeting from God , blessed and good .
