I have just read this.....

....Under Islam, a stranger is referred to as “Ibn Al-Sabil” (wayfarer) who is paid a lot of attention by Islam. The Qur’an considers that it is an act of righteousness to give money to a wayfarer.

We read the following verse:

Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah , the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveller… (Al-Baqarah 2:177)

The Qur’an orders doing good to wayfarers.

We read the following verse:

Worship Allah and associate nothing with Him, and to parents do good, and to relatives, orphans, the needy, the near neighbour, the neighbour farther away, the companion at your side, the traveller… (An-Nisaa’ 4:36)

A wayfarer was entitled to a share in the war booty. In the Qur’an, we read the following verse:

And know that anything you obtain of war booty – then indeed, for Allah is one fifth of it and for the Messenger and for [his] near relatives and the orphans, the needy, and the [stranded] traveller… (Al-Anfal 8:41)

A wayfarer was also entitled to a share in the Zakah expenditures. In the Qur’an, we read the following verse:

Zakah expenditures are only for the poor and for the needy and for those employed to collect [zakah] and for bringing hearts together [for Islam] and for freeing captives [or slaves] and for those in debt and for the cause of Allah and for the [stranded] traveler – an obligation [imposed] by Allah. (At-Tawbah 9:60)

Prophet Muhammad urged Muslims to give money to the wayfarers. Abu Said Al-Khudry reports that the Messenger of Allah said: “This money is green and sweet. It is a good companion of the Muslim who gives from it to the orphan, the needy and the wayfarers.” (Ahmad)

According to Prophet Muhammad (peace be upon him), the one who denies a wayfarer his surplus water is one of three persons at whom God will not look on the Day of Judgment.

I wish I could tell you that this is the way I've been treated over the last year.  I respect all who I met except for those who deliberately lied and cheated, and the few who act as if I'm not even in the same room.  I have received much hospitality, but not in the way described above.
