[Machine] Abu Musa sought permission from Umar three times, but Umar did not grant him permission. So Abu Musa returned and informed Umar of this. Umar asked him, "What prevented you?" Abu Musa replied, "I heard the Messenger of Allah ﷺ saying, 'If any one of you seeks permission three times and is not granted permission, then let him go back.'" Umar said, "Come to me with proof of this, or else Hammad will punish you." Abu Musa left and entered the mosque, then went to the gathering of the Ansar, and narrated to them the incident and what Umar said to him. They said, "None of us will stand with you except our youngest member." So Abu Sa'eed Al-Khudri stood with him and testified. Umar said to him, "We do not accuse you, but the narration from the Messenger of Allah ﷺ is severe."
أَنَّ أَبَا مُوسَى اسْتَأْذَنَ عَلَى عُمَرَ ثَلَاثَ مَرَّاتٍ فَلَمْ يُؤْذَنْ لَهُ فَرَجَعَ فَبَلَغَ ذَلِكَ عُمَرَ فَقَالَ مَا رَدَّكَ؟ فَقَالَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِذَا اسْتَأْذَنَ أَحَدُكُمْ ثَلَاثَ مَرَّاتٍ فَلَمْ يُؤْذَنْ لَهُ فَلْيَرْجِعْ» فَقَالَ لِتَجِئْنِي عَلَى هَذَا بِبَيِّنَةٍ وَإِلَّا قَالَ حَمَّادٌ تَوَعَّدَهُ قَالَ فَانْصَرَفَ فَدَخَلَ الْمَسْجِدَ فَأَتَى مَجْلِسَ الْأَنْصَارِ فَقَصَّ عَلَيْهِمُ الْقِصَّةَ مَا قَالَ لِعُمَرَ وَمَا قَالَ لَهُ عُمَرُ فَقَالُوا لَا يَقُومُ مَعَكَ إِلَّا أَصْغَرُنَا فَقَامَ مَعَهُ أَبُو سَعِيدٍ الْخُدْرِيُّ فَشَهِدَ فَقَالَ لَهُ عُمَرُ إِنَّا لَا نَتَّهِمُكَ وَلَكِنَّ الْحَدِيثَ عَنْ رَسُولِ اللَّهِ ﷺ شَدِيدٌ
