Once the Messenger of Allah ﷺ intended to go on an expedition. He said: O group of the emigrants (Muhajirun) and the helpers (Ansar), among your brethren there are people who have neither property nor family. So one of you should take with him two or three persons; with me. I also rode on my camel by turns like one of them. (Using translation from Abū Dāʾūd 2534)
عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ أَرَادَ أَنْ يَغْزُوَ فَقَالَ يَا مَعْشَرَ الْمُهَاجِرِينَ وَالْأَنْصَارِ إِنَّ مِنْ إِخْوَانِكُمْ قَوْمًا لَيْسَ لَهُمْ مَالٌ وَلَا عَشِيرَةٌ فَلْيَضُمَّ أَحَدُكُمْ إِلَيْهِ الرَّجُلَيْنِ أَوِ الثَّلَاثَةَ فَمَا لِأَحَدِنَا مِنْ ظَهْرِ جَمَلٍ إِلَّا عُقْبَةٌ كَعُقْبَةِ أَحَدِهِمْ قَالَ فَضَمَمْتُ إِلِيَّ اثْنَيْنِ أَوْ ثَلَاثَةً مَا لِي عُقْبَةٌ إِلَّا كَعُقْبَةِ أَحَدِهِمْ
