The Prophet ﷺ said, "A Muslim is the one who avoids harming Muslims with his tongue or his hands. And a Muhajir (an emigrant) is the one who gives up (abandons) all what Allah has forbidden."  

قَالَ النَّبِيُّ ﷺ الْمُسْلِمُ مَنْ سَلِمَ الْمُسْلِمُونَ مِنْ لِسَانِهِ وَيَدِهِ وَالْمُهَاجِرُ مَنْ هَجَرَ مَا نَهَى اللَّهُ عَنْهُ
