"When the Messenger of Allah ﷺ arrived in Al-Madinah the Muhajirun came to him and said: 'O Messenger of Allah! We have not seen a people more willing to sacrifice when having a lot, nor more patient when having a little than the people whom we are staying among. Our provisions are so sufficient, and we share with them in their produce such that we fear that all our reward is gone. So the Prophet ﷺ said: "No. As long as you supplicate to Allah for them and praise (show gratitude to) them(for it)." (Using translation from Tirmidhī 2487)
قَالَ الْمُهَاجِرُونَ يَا رَسُولَ اللهِ مَا رَأَيْنَا مِثْلَ قَوْمٍ قَدِمْنَا عَلَيْهِمُ الْمَدِينَةَ أَحْسَنَ بَذْلًا مِنْ كَثِيرٍ وَلَا أَحْسَنَ مُوَاسَاةً مِنْ قَلِيلٍ قَدْ كَفَوْنَا الْمُؤْنَةَ وَأَشْرَكُونَا فِي الْمَهْنَأِ فَقَدْ خَشِينَا أَنْ يَكُونُوا يَذْهَبُونَ بِالْأَجْرِ كُلِّهِ فَقَالَ رَسُولُ اللهِ ﷺ كَلَّا مَا أَثْنَيْتُمْ بِهِ عَلَيْهِمْ وَدَعَوْتُمُ اللهَ لَهُمْ
