عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ كُنْتُ فِي حَلْقَةٍ مِنْ حَلَقِ الْأَنْصَارِ فَجَاءَنَا أَبُو مُوسَى رَضِيَ اللَّهُ عَنْهُ كَأَنَّهُ مَذْعُورٌ فَقَالَ إِنَّ عُمَرَ أَمَرَنِي أَنْ آتِيَهُ فَأَتَيْتُهُ فَاسْتَأْذَنْتُ ثَلَاثًا فَلَمْ يُؤْذَنْ لِي فَرَجَعْتُ وَقَدْ قَالَ ذَلِكَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”مَنِ اسْتَأْذَنَ ثَلَاثًا فَلَمْ يُؤْذَنْ لَهُ فَلْيَرْجِعْ“ فَقَالَ لَتَجِيئَنَّ بِبَيِّنَةٍ عَلَى الَّذِي تَقُولُ وَإِلَّا أَوْجَعْتُكَ قَالَ أَبُو سَعِيدٍ فَأَتَانَا أَبُو مُوسَى مَذْعُورًا أَوْ قَالَ فَزِعًا فَقَالَ أَسْتَشْهِدُكُمْ فَقَالَ أُبَيُّ بْنُ كَعْبٍ رَضِيَ اللَّهُ عَنْهُ لَا يَقُومُ مَعَكَ إِلَّا أَصْغَرُ الْقَوْمِ قَالَ أَبُو سَعِيدٍ وَكُنْتُ أَصْغَرَهُمْ فَقُمْتُ مَعَهُ وَشَهِدْتُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ”مَنِ اسْتَأْذَنَ ثَلَاثًا فَلَمْ يُؤْذَنْ لَهُ فَلْيَرْجِعْ“
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him), who says: I was sitting in a gathering of the Ansar when Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) came to us, and he seemed somewhat frightened. He said, "In fact, Sayyiduna Umar (may Allah be pleased with him) had called me to him, so I went to him and sought permission three times, but when I was not granted permission, I turned back, because the Messenger of Allah (peace and blessings be upon him) said: 'Whoever seeks permission three times from someone and is not granted permission, let him return.' When I informed Sayyiduna Umar (may Allah be pleased with him) of this hadith, he said: 'Bring proof of this, otherwise I will punish you.' So I have come to seek testimony." Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) said: "The youngest among us will stand with you for this." Sayyiduna Abu Sa'id (may Allah be pleased with him) said: "I was the youngest, so I stood up and testified that the Messenger of Allah (peace and blessings be upon him) said: 'Whoever seeks permission three times and is not granted permission, let him return.'"
