The Prophet ﷺ said: Leave the Abyssinians alone as long as they leave you alone, for it is only the Abyssinian with short legs who will seek to take out the treasure of the Ka'bah.  

عَنِ النَّبِيِّ ﷺ قَالَ اتْرُكُوا الْحَبَشَةَ مَا تَرَكُوكُمْ فَإِنَّهُ لاَ يَسْتَخْرِجُ كَنْزَ الْكَعْبَةِ إِلاَّ ذُو السُّوَيْقَتَيْنِ مِنَ الْحَبَشَةِ
