(An ally of the tribe of Bani 'Amir bin Lu'ai and one of those who had witnessed the battle of Badr with Messenger of Allah ﷺ) Messenger of Allah ﷺ sent Abu 'Ubaida bin AlJarrah to Bahrain to collect the Jizya tax. Messenger of Allah ﷺ had concluded a peace treaty with the people of Bahrain and appointed Al 'Ala bin Al-Hadrami as their chief; Abu Ubaida arrived from Bahrain with the money. The Ansar heard of Abu 'Ubaida's arrival which coincided with the Fajr (morning) prayer led by Messenger of Allah ﷺ. When the Prophet ﷺ finished the prayer, they came to him. Messenger of Allah ﷺ smiled when he saw them and said, "I think you have heard of the arrival of Abu 'Ubaida and that he has brought something." They replied, "Yes, O Messenger of Allah ﷺ! " He said, "Have the good news, and hope for what will please you. By Allah, I am not afraid that you will become poor, but I am afraid that worldly wealth will be given to you in abundance as it was given to those (nations) before you, and you will start competing each other for it as the previous nations competed for it, and then it will divert you (from good) as it diverted them." ' (Using translation from Bukhārī 6425)
أنَّهُ أَخْبَرَهُ أَنَّ عَمْرَو بْنَ عَوْفٍ وَهُوَ حَلِيفُ بَنِي عَامِرٍ وَكَانَ شَهِدَ بَدْرًا مَعَ رَسُولِ اللهِ ﷺ أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ بَعَثَ أَبَا عُبَيْدَةَ بْنَ الْجَرَّاحِ إِلَى الْبَحْرَيْنِ فَأَتَى بِجِزْيَتِهَا وَكَانَ رَسُولُ اللهِ ﷺ هُوَ صَالَحَ الْبَحْرَيْنَ أَمَّرَ عَلَيْهِمْ الْعَلَاءَ بْنَ الْحَضْرَمِيِّ فَقَدِمَ أَبُو عُبَيْدَةَ بِمَالٍ مِنَ الْبَحْرَيْنِ فَسَمِعَتِ الْأَنْصَارُ بِقُدُومِهِ فَوَافَتْ صَلَاةَ الْفَجْرِ مَعَ رَسُولِ اللهِ ﷺ فَلَمَّا صَلَّى انْصَرَفَ فَتَعَرَّضُوا لَهُ فَتَبَسَّمَ حِينَ رَآهُمْ وَقَالَ «أَظُنُّكُمْ سَمِعْتُمْ بِقُدُومِ أَبِي عُبَيْدَةَ وَأَنَّهُ جَاءَ بِشَيْءٍ؟» قَالُوا أَجَلْ قَالَ «فَأَبْشِرُوا وَأْمَلُوا مَا يَسُرُّكُمْ فَوَاللهِ مَا الْفَقْرُ أَخْشَى عَلَيْكُمْ وَلَكِنْ أَخْشَى أَنْ تُبْسَطَ الدُّنْيَا عَلَيْكُمْ كَمَا بُسِطَتْ عَلَى مَنْ قَبْلَكُمْ فَتَنَافَسُوهَا كَمَا تَنَافَسُوهَا وَيُلْهِيكُمْ كَمَا أَلْهَتْهُمْ»
