Allah's Apostle said, ''While I was sleeping I saw (in a dream) some people wearing shirts of which some were reaching up to the breasts only while others were even shorter than that. Umar bin Al-Khattab was shown wearing a shirt that he was dragging.'' The people asked, ''How did you interpret it? (What is its interpretation) O Allah's Apostle?'' He (the Prophet ) replied, ''It is the Religion.''
