Muhammad said: It is said: a man is junub (in a state of major ritual impurity) and a woman is junub, and likewise in the dual and plural forms; this is the most eloquent of the linguistic forms. "And if you are sick or on a journey" up to His saying: "then wipe your faces and hands with it," its interpretation has already passed in Surat An-Nisa.
"Allah does not intend to make any difficulty for you" meaning: any distress.
"But He intends to purify you" from sins, "and to complete His favor upon you that you may be grateful," meaning: so that you may be grateful, and thus enter Paradise. Surat Al-Ma'idah from verse (7) to verse (10).
