[Machine] The Messenger of Allah ﷺ said, "Do you know who the Muslim is?" They said, "Allah and His Messenger know best." He said, "The Muslims are those whom other Muslims are safe from their tongue and hand." They said, "Then who is the believer?" He said, "The believers are those whom other believers trust with their lives and wealth." They said, "Then who is the emigrant?" He said, "The emigrant is the one who abandons evil and avoids it." Abu Al-Qasim said, "The people of Egypt say Musa bin Ali bin Rabah, while others say Musa bin Ali. And it has caused difficulty for those who named him 'Ali."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «أَتَدْرُونَ مَا الْمُسْلِمُ؟» قَالُوا اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ مَنْ سَلِمَ الْمُسْلِمُونَ مِنْ لِسَانِهِ وَيَدِهِ قَالُوا فَمَنِ الْمُؤْمِنُ؟ قَالَ «مَنْ أَمِنَهُ الْمُؤْمِنُونَ عَلَى أَنْفُسِهِمْ وَأَمْوَالِهِمْ» قَالُوا فَمَنِ الْمُهَاجِرُ؟ قَالَ «مَنْ هَجَرَ السُّوءَ فَاجْتَنَبَهُ» قَالَ أَبُو الْقَاسِمِ أَهْلُ مِصْرَ يَقُولُونَ مُوسَى بْنُ عَلِيِّ بْنِ رَبَاحٍ وَسَائِرُ النَّاسِ يَقُولُونَ مُوسَى بْنُ عُلِيٍّ وَقَدْ حَرَّجَ عَلَى مَنْ سَمَّاهُ عُلَيًّا
