Husain said: "A beggar came to Ibn 'Abbas to beg from him. Ibn 'Abbas said to the beggar: 'Do you testify to La Ilaha Illallah?' He said: 'Yes.' He said: 'Do you testify that Muhammad is the Messenfger of Allah?' He said: 'Yes.' He said: 'You fast(the month of) Ramadan?' He said: 'Yes?' He said: 'You asked, and the one who asked has a right, so you have a right upon us that we give you.' So he gave him a garment then said: 'I heard the Messenger of Allah (s.a.w) saying: "No Muslim clothes a Muslim with a garment except that he is under the protection of Allah as long as a shred from it remains upon him."
