[Machine] The Messenger of Allah ﷺ sent a group and appointed 'Ubaydah ibn al-Harith over them. When he set out to lead them, he wept profusely towards the Messenger of Allah ﷺ. So the Messenger of Allah ﷺ sent a man named 'Abdullah ibn Jahsh in his place and wrote a letter for him. He ordered him not to read it until he reached a certain place, and not to force any of his companions to join him on the journey. So when he reached that place, he read the letter and contemplated it. He said, "I hear and obey Allah and His Messenger." So one of his companions returned, and the rest of them continued with him. They encountered Ibn al-Hadhrami and killed him without realizing it was Rajab or Jumada al-Akhirah (months). So the polytheists said, "They killed him in the sacred month." And the verse was revealed: "They ask you about the sacred month - about fighting therein. Say, 'Fighting therein is great [sin], but averting [people] from the way of Allah and disbelief in Him and [preventing access to] al-Masjid al-Haram and the expulsion of its people therefrom are greater [evil] in the sight of Allah.'" [Quran 2:217] until His saying: "And fitnah is greater than killing." [Quran 2:217] Some Muslims said, "If they were in the right, they would have received a reward." So the verse was revealed: "Indeed, those who have believed and those who have emigrated and fought in the cause of Allah - those expect the mercy of Allah. And Allah is Forgiving and Merciful." [Quran 2:218]
بَعَثَ رَسُولُ اللهِ ﷺ رَهْطًا وَاسْتَعْمَلَ عَلَيْهِمْ عُبَيْدَةَ بْنَ الْحَارِثِ قَالَ فَلَمَّا انْطَلَقَ لِيَتَوَجَّهَ بَكَى صَبَابَةً إِلَى رَسُولِ اللهِ ﷺ فَبَعَثَ مَكَانَهُ رَجُلًا يُقَالُ لَهُ عَبْدُ اللهِ بْنُ جَحْشٍ وَكَتَبَ لَهُ كِتَابًا وَأَمَرَهُ أَنْ لَا يَقْرَأَهُ إِلَّا لِمَكَانِ كَذَا وَكَذَا لَا تُكْرِهَنَّ أَحَدًا مِنْ أَصْحَابِكَ عَلَى الْمَسِيرِ مَعَكَ فَلَمَّا صَارَ إِلَى ذَلِكَ الْمَوْضِعِ قَرَأَ الْكِتَابَ وَاسْتَرْجَعَ قَالَ سَمْعًا وَطَاعَةً لِلَّهِ وَرَسُولِهِ قَالَ فَرَجَّعَ رَجُلًا مِنْ أَصْحَابِهِ وَمَضَى بَقِيَّتُهُمْ مَعَهُ فَلَقُوا ابْنَ الْحَضْرَمِيِّ فَقَتَلُوهُ فَلَمْ يَدْرِ ذَلِكَ مِنْ رَجَبٍ أَوْ مِنْ جُمَادَى الْآخِرَةِ فَقَالَ الْمُشْرِكُونَ قَتَلَهُمْ فِي الشَّهْرِ الْحَرَامِ فَنَزَلَتْ {يَسْأَلُونَكَ عَنِ الشَّهْرِ الْحَرَامِ قِتَالٍ فِيهِ قُلْ قِتَالٌ فِيهِ كَبِيرٌ} [البقرة 217] إِلَى قَولِهِ {وَالْفِتْنَةُ أَكْبَرُ مِنَ الْقَتْلِ} [البقرة 217] قَالَ فَقَالَ بَعْضُ الْمُسْلِمِينَ لَئِنْ كَانُوا أَصَابُوا خَيْرًا مَا لَهُمْ أَجْرٌ فَنَزَلَتْ {إِنَّ الَّذِينَ آمَنُوا وَالَّذِينَ هَاجَرُوا وَجَاهَدُوا فِي سَبِيلِ اللهِ أُولَئِكَ يَرْجُونَ رَحْمَةَ اللهِ وَاللهُ غَفُورٌ رَحِيمٌ}
