Does the saying of Prophet Abraham to his wife Sarah, "By God, there is no believer on earth other than me and you," have an interpretation?

The intent of Abraham's (peace be upon him) statement to Sarah: "There is no believer on the face of the earth other than you and me," was that she was his sister in faith. And at the time they entered the land of that tyrant, there was no believer there except Abraham and Sarah. It is also possible that he denied knowledge of the existence of any other believer. Some commentators said that among the injustices of that tyrant was that he would accost married women and forcefully take them from their husbands, but he would not accost unmarried women. For this reason, Abraham said: "If he knows you are my wife, he will overpower me concerning you."
