'Amr b. 'Auf, who was an ally of Banu 'Amir b. Luwayy (and he was one amongst them) who participated in Badr along with Allah's Messenger ﷺ. reported that, Messenger of Allah ﷺ sent Abu Ubaida b. Jarrah to Bahrain for collecting Jizya and Messenger of Allah ﷺ had made a truce with the people of Bahrain and had appointed 'Ala' b. Hadrami and Abu Ubaida (for this purpose). They came with wealth from Bahrain and the Ansar beard about the arrival of Abu Ubaida and they had observed the dawn prayer along with Messenger of Allah ﷺ, and when Messenger of Allah ﷺ had finished the prayer they (the Ansar) came before him and Messenger of Allah ﷺ smiled as he saw them and then said: I think you have heard about the arrival of Abu Ubaida with goods from Bahrain. They said: Allah's Messenger. yes, it is so. Thereupon he said: Be happy and be hopeful of that what gives you delight. By Allah, it is not the poverty about which I fear in regard to you but I am afraid in your case that (the worldly) riches way be given to you as were given to those who had gone before you and you begin to vie with one another for them as they vied for them. and these may destroy you as these destroyed them.

حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى بْنِ عَبْدِ اللَّهِ، - يَعْنِي ابْنَ حَرْمَلَةَ بْنِ عِمْرَانَ التُّجِيبِيَّ -
أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، أَنَّ الْمِسْوَرَ بْنَ مَخْرَمَةَ،
أَخْبَرَهُ أَنَّ عَمْرَو بْنَ عَوْفٍ وَهُوَ حَلِيفُ بَنِي عَامِرِ بْنِ لُؤَىٍّ وَكَانَ شَهِدَ بَدْرًا مَعَ رَسُولِ
اللَّهِ ﷺ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ أَبَا عُبَيْدَةَ بْنَ
الْجَرَّاحِ إِلَى الْبَحْرَيْنِ يَأْتِي بِجِزْيَتِهَا وَكَانَ رَسُولُ اللَّهِ ﷺ هُوَ صَالَحَ
أَهْلَ الْبَحْرَيْنِ وَأَمَّرَ عَلَيْهِمُ الْعَلاَءَ بْنَ الْحَضْرَمِيِّ فَقَدِمَ أَبُو عُبَيْدَةَ بِمَالٍ مِنَ الْبَحْرَيْنِ فَسَمِعَتِ
الأَنْصَارُ بِقُدُومِ أَبِي عُبَيْدَةَ فَوَافَوْا صَلاَةَ الْفَجْرِ مَعَ رَسُولِ اللَّهِ ﷺ فَلَمَّا
صَلَّى رَسُولُ اللَّهِ ﷺ انْصَرَفَ فَتَعَرَّضُوا لَهُ فَتَبَسَّمَ رَسُولُ اللَّهِ صلى الله
عليه وسلم حِينَ رَآهُمْ ثُمَّ قَالَ " أَظُنُّكُمْ سَمِعْتُمْ أَنَّ أَبَا عُبَيْدَةَ قَدِمَ بِشَىْءٍ مِنَ الْبَحْرَيْنِ "
. فَقَالُوا أَجَلْ يَا رَسُولَ اللَّهِ قَالَ " " فَأَبْشِرُوا وَأَمِّلُوا مَا يَسُرُّكُمْ فَوَاللَّهِ مَا الْفَقْرَ أَخْشَى
عَلَيْكُمْ . وَلَكِنِّي أَخْشَى عَلَيْكُمْ أَنْ تُبْسَطَ الدُّنْيَا عَلَيْكُمْ كَمَا بُسِطَتْ عَلَى مَنْ كَانَ قَبْلَكُمْ فَتَنَافَسُوهَا
كَمَا تَنَافَسُوهَا وَتُهْلِكَكُمْ كَمَا أَهْلَكَتْهُمْ " .
