“Cut your hair short. There are three things which one will never abandon doing, once he starts doing them. The first one is cutting his hair. Once he cuts his hair short and feels how comfortable it is, he will never again let his hair grow long. The second one is cutting short his robe. Whoever wears a long robe, and then cuts it a little to make it shorter will feel so comfortable that he will never again wear a long robe. The third one is related to marriage and divorce. Whoever divorces his free wife, and then marries a maid, will never again marry a free woman, since the maid expects very little and always obeys his orders. God the Almighty told the Prophet: “And thy garments keep free from stain!” [The Holy Quran: Mudaththir 74:4], This was revealed even though the Prophet's garment was clean. God just ordered him to shorten it a little bit.”
