It was rarely that the Messenger of Allah ﷺ set out on a journey on any day but on a Thursday. (Using translation from Abū Dāʾūd 2605)  

«قَلَّمَا كَانَ رَسُولُ اللهِ ﷺ» يَخْرُجُ فِي سَفَرٍ إِلَّا يَوْمَ الْخَمِيسِ  

[Machine] I heard the Messenger of Allah ﷺ say, "When Egypt is opened, treat the Copts well, for they have a covenant and mercy." Meaning that Umm Isma'il (the mother of Isma'il) was one of them.  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِذَا فُتِحَتْ مِصْرُ فَاسْتَوْصُوا بِالْقِبْطِ خَيْرًا فَإِنَّ لَهُمْ ذِمَّةً وَرَحِمًا» يَعْنِي أَنَّ أُمَّ إِسْمَاعِيلَ كَانَتْ مِنْهُمْ  

[Machine] That the Messenger of Allah ﷺ said, "When you conquer Egypt, treat the Copts well, for indeed they have an agreement and mercy (protection)."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِذَا فَتَحْتُمْ مِصْرَ فَاسْتَوْصُوا بِالْقِبْطِ خَيْرًا فَإِنَّ لَهُمْ ذِمَّةً وَرَحِمًا»
