Sayyiduna Miswar bin Makhramah (may Allah be pleased with him) narrated: Umar bin Khattab (may Allah be pleased with him) said to Abdur Rahman bin Awf (may Allah be pleased with him): Is this verse not among the verses revealed to us: «جاهدوا كما جاهدتم أول مرة» "Just as you strove in jihad before, so should you strive now." He replied: Yes, this is the verse. Umar said: But I did not find this verse in the Mushaf. He replied: This verse is among the abrogated verses of the Qur'an. Umar said: We fear that people may not become disbelievers. He replied: Whatever Allah wills will happen. Umar said: If people become disbelievers, then they will become the leaders of such-and-such tribe and the ministers of such-and-such tribe.
