Safwan ibn Umayyah sent him with some milk, a young gazelle and some small cucumbers to the Messenger of Allah ﷺ when he was in the upper part of Mecca. I entered but I did not give a salutation. He said: Go back and say: "Peace be upon you"! This happened after Safwan ibn Umayyah and embraced Islam. Amr said: Ibn Safwan told me all this on the authority of Kaladah ibn Hanbal, and he did not say: I heard it from him. Abu Dawud said: Yahya b. Habib said: Umayyah b. Safwan. He did not say: I heard from Kaladah b. Hanbal. Yahya also said: 'Amr b. 'Abd Allah b. Safwan told him that Kaladah b. al-Hanbal told him.  

أَنَّ صَفْوَانَ بْنَ أُمَيَّةَ بَعَثَهُ إِلَى رَسُولِ اللَّهِ ﷺ بِلَبَنٍ وَجِدَايَةٍ وَضَغَابِيسَ وَالنَّبِيُّ ﷺ بِأَعْلَى مَكَّةَ فَدَخَلْتُ وَلَمْ أُسَلِّمْ فَقَالَ ارْجِعْ فَقُلِ السَّلاَمُ عَلَيْكُمْ وَذَاكَ بَعْدَ مَا أَسْلَمَ صَفْوَانُ بْنُ أُمَيَّةَ قَالَ عَمْرٌو وَأَخْبَرَنِي ابْنُ صَفْوَانَ بِهَذَا أَجْمَعَ عَنْ كَلَدَةَ بْنِ حَنْبَلٍ وَلَمْ يَقُلْ سَمِعْتُهُ مِنْهُ  

A man of Banu Amir told that he asked the Prophet ﷺ for permission (to enter the house) when he was in the house, saying: May I enter ? The Prophet ﷺ said to his servant: Go out to this (man) and teach him how to ask permission to enter the house, and say to him: "Say : Peace be upon you. May I enter?" The man heard it and said: Peace be upon you! May I enter ? The Prophet ﷺ permitted him and he entered.  

أَنَّهُ اسْتَأْذَنَ عَلَى النَّبِيِّ ﷺ وَهُوَ فِي بَيْتٍ فَقَالَ أَلِجُ فَقَالَ النَّبِيُّ ﷺ لِخَادِمِهِ اخْرُجْ إِلَى هَذَا فَعَلِّمْهُ الاِسْتِئْذَانَ فَقُلْ لَهُ قُلِ السَّلاَمُ عَلَيْكُمْ أَأَدْخُلُ فَسَمِعَهُ الرَّجُلُ فَقَالَ السَّلاَمُ عَلَيْكُمْ أَأَدْخُلُ فَأَذِنَ لَهُ النَّبِيُّ ﷺ فَدَخَلَ  

Similarly, Musaddad transmitted it to us saying that Abu 'Awanah related it to us from Mansur. He did not say: "a man of Banu 'Amir".  

أَنَّ رَجُلاً مِنْ بَنِي عَامِرٍ اسْتَأْذَنَ عَلَى النَّبِيِّ ﷺ بِمَعْنَاهُ  

I heard it and so I said: Peace be upon you. May I enter?  

أَنَّهُ اسْتَأْذَنَ عَلَى النَّبِيِّ ﷺ بِمَعْنَاهُ قَالَ فَسَمِعْتُهُ فَقُلْتُ السَّلاَمُ عَلَيْكُمْ أَأَدْخُلُ
