Ash-Sha'bi said, "A man came to 'Abdullah ibn 'Amr when there were some people sitting with him. He stepped over them in order to reach him. They stopped him and 'Abdullah said, 'Leave the man.' He approached until he sat with him and then said, 'Tell me something which you heard from the Messenger of Allah, (ﷺ).' 'Abdullah said, 'I heard the Messenger of Allah, (ﷺ), say, "A Muslim is the one from whose tongue and hand the Muslims are safe. An emigrant (muhajir) is someone who abandons what Allah has forbidden."'"

حَدَّثَنَا مُحَمَّدُ بْنُ سَلاَمٍ، قَالَ‏:‏ أَخْبَرَنَا عَبْدَةُ، عَنِ ابْنِ أَبِي خَالِدٍ، عَنِ الشَّعْبِيِّ قَالَ‏:‏ جَاءَ رَجُلٌ إِلَى عَبْدِ اللهِ بْنِ عَمْرٍو، وَعِنْدَهُ الْقَوْمُ جُلُوسٌ، يَتَخَطَّى إِلَيْهِ، فَمَنَعُوهُ، فَقَالَ‏:‏ اتْرُكُوا الرَّجُلَ، فَجَاءَ حَتَّى جَلَسَ إِلَيْهِ، فَقَالَ‏:‏ أَخْبِرْنِي بِشَيْءٍ سَمِعْتَهُ مِنْ رَسُولِ اللهِ صلى الله عليه وسلم، قَالَ‏:‏ سَمِعْتُ رَسُولَ اللهِ صلى الله عليه وسلم يَقُولُ‏:‏ الْمُسْلِمُ مِنْ سَلِمَ الْمُسْلِمُونَ مِنْ لِسَانِهِ وَيَدِهِ، وَالْمُهَاجِرُ مَنْ هَجَرَ مَا نَهَى اللَّهُ عَنْهُ‏.‏
