عَن كَعْب بْنِ مَالِكٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ يَوْمَ الْخَمِيسِ فِي غَزْوَةِ تَبُوكَ وَكَانَ يُحِبُّ أَنْ يَخْرُجَ يَوْمَ الْخَمِيسِ. رَوَاهُ البُخَارِيّ

Jabir said

I was with the Prophet on a journey, and when we came to Medina he said to me, "Enter the mosque and pray two rak'as in it." Bukhari transmitted it.
