[Machine] Abu Musa sought permission from Umar, who replied, "One, two, three" and then Abu Musa returned. Umar said to him, "You must come with evidence for this, or I will take action." Abu Musa replied as if to say, "I will make you regret this." Umar said, "Fine, go ahead." Then Abu Musa went to a gathering where the Ansar were present and mentioned this to them. He said, "Do you not know that the Messenger of Allah, ﷺ , said that if anyone seeks permission three times and is not granted permission, they should go back?" They replied, "Indeed, only our youngest ones go with you." Abu Sa'eed al-Khudri then stood up and told Umar, "This is Abu Sa'eed, leave him alone."
إِنَّ أَبَا مُوسَى اسْتَأْذَنَ عَلَى عُمَرَ قَالَ وَاحِدَةً ثِنْتَيْنِ ثَلَاثًا ثُمَّ رَجَعَ أَبُو مُوسَى فَقَالَ لَهُ عُمَرُ لَتَأْتِيَنَّ عَلَى هَذَا بِبَيِّنَةٍ أَوْ لَأَفْعَلَنَّ قَالَ كَأَنَّهُ يَقُولُ أَجْعَلُكَ نَكَالًا فِي الْآفَاقِ قَالَ فَانْطَلَقَ أَبُو مُوسَى إِلَى مَجْلِسٍ فِيهِ الْأَنْصَارُ فَذَكَرَ ذَلِكَ لَهُمْ فَقَالَ أَلَمْ تَعْلَمُوا أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا اسْتَأْذَنَ أَحَدُكُمْ ثَلَاثًا فَلَمْ يُؤْذَنْ لَهُ فَلْيَرْجِعْ قَالُوا بَلَى لَا يَقُومُ مَعَكَ إِلَّا أَصْغَرُنَا قَالَ فَقَامَ أَبُو سَعِيدٍ الْخُدْرِيُّ إِلَى عُمَرَ فَقَالَ هَذَا أَبُو سَعِيدٍ فَخَلَّى عَنْهُ
