[Machine] When the Messenger of Allah ﷺ left Makkah, Abu Bakr said, "Indeed, we belong to Allah, and indeed to Him we will return." The Messenger of Allah ﷺ was expelled so that he could be destroyed entirely. But when this verse was revealed, "Permission [to fight] has been given to those who are being fought, because they were wronged. And indeed, Allah is competent to give them victory. [They are] those who have been expelled from their homes," Abu Bakr knew that there would be fighting.
لَمَّا خَرَجَ رَسُولُ اللهِ ﷺ مِنْ مَكَّةَ قَالَ أَبُو بَكْرٍ إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ أُخْرِجَ رَسُولُ اللهِ ﷺ لَيَهْلِكُنَّ جَمِيعًا فَلَمَّا أُنْزِلَتْ هَذِهِ الْآيَةُ {أُذِنَ لِلَّذِينَ يُقَاتَلُونَ بَأَنَّهُمْ ظُلِمُوا وَإِنَّ اللهَ عَلَى نَصْرِهِمْ لَقَدِيرٌ} {الَّذِينَ أُخْرِجُوا مِنْ دِيَارِهِمْ} عَرَفَ أَبُو بَكْرٍ أَنَّهُ سَيَكُونُ قِتَالٌ
