"Anas and Abdullah reported God's Messenger as saying, All creatures are God's children, and those dearest to God are those who treat His children kindly."
Hadith of Baihaqi
"Seek for mankind that of which you are desirous for yourself, that you may be a believer; treat well as a neighbor the one who lives near you, that you may be a Muslim [one who submits to God]."
Sukhanan-i-Muhammad (Teheran, 1938)
"But how many were the prophets We sent amongst the peoples of old? And never came there a prophet to them but they mocked him. So We destroyed [them]- stronger in power than these;- and [thus] has passed on the Parable of the peoples of old."
