[Machine] Abu Musa asked Umar for permission three times, but he was not granted permission. So he came back and met Umar, who asked him, "What made you return?" Abu Musa said, "I heard the Messenger of Allah ﷺ say, 'Anyone who seeks permission three times and is not granted permission, should return.' Umar said, 'You must bring clear evidence for this, or else I will take action.' So Abu Musa went to his people and sought their support, and they testified in his favor. Umar then allowed him to go his way."
اسْتَأْذَنَ أَبُو مُوسَى عَلَى عُمَرَ ثَلَاثًا فَلَمْ يُؤْذَنْ لَهُ فَرَجَعَ فَلَقِيَهُ عُمَرُ فَقَالَ مَا شَأْنُكَ رَجَعْتَ؟ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مِنْ اسْتَأْذَنَ ثَلَاثًا فَلَمْ يُؤْذَنْ لَهُ فَلْيَرْجِعْ فَقَالَ لَتَأْتِيَنَّ عَلَى هَذَا بِبَيِّنَةٍ أَوْ لَأَفْعَلَنَّ وَلَأَفْعَلَنَّ فَأَتَى مَجْلِسَ قَوْمِهِ فَنَاشَدَهُمُ اللهَ تَعَالَى فَقُلْتُ أَنَا مَعَكَ فَشَهِدُوا لَهُ بِذَلِكَ فَخَلَّى سَبِيلَهُ
