[Machine] He used to say that rarely did the Messenger of Allah ﷺ go on a journey for jihad or other reasons except on a Thursday. They have mentioned it in the authentic narration in the hadith of Tawbah of Ka'b ibn Malik.  

البيهقي:١٠٣٠٧ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو زَكَرِيَّا بْنُ أَبِي إِسْحَاقَ وَأَبُو بَكْرِ بْنُ الْحَسَنِ الْحِيرِيُّ قَالُوا ثنا أَبُو الْعَبَّاسِ أنا مُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ عَبْدِ الْحَكَمِ أَخْبَرَنِي ابْنُ وَهْبٍ أَخْبَرَنِي يُونُسُ بْنُ يَزِيدَ عَنِ ابْنِ شِهَابٍ قَالَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ كَعْبِ بْنِ مَالِكٍ عَنْ أَبِيهِ

أَنَّهُ كَانَ يَقُولُ قَلَّمَا كَانَ رَسُولُ اللهِ ﷺ يَخْرُجُ فِي سَفَرٍ لِجِهَادٍ وَغَيْرِهِ إِلَّا يَوْمَ الْخَمِيسِ أَخْرَجَاهُ فِي الصَّحِيحِ فِي حَدِيثِ تَوْبَةِ كَعْبِ بْنِ مَالِكٍ
