[4:156] And for their disbelief, and their uttering against Mary a tremendous calumny.
Disregard for the limit is error, just as diminishment or subtraction from the truth is error. Some people slandered Mary and accused her of fornication. Others transgressed the limit even further in a terrible calumny, saying her son was the son of God. Both of these groups fell into error.
It is said that Mary (r) was a friend (waliyya) of God through whom two groups became unfortunate: those who exceed all bounds (ahl al-ifrā?) and those who fall short (ahl al-tafrī?) Just as there are those who reject His friends in lacking respect for them, there are those who believe in them and will therefore suffer no increase in difficulties. It is among this group that most of the great rise in rank.
