Going to the church
From Aslam the servant of Umar, that Umar ibn al-Khattaab arrived in Shaam, a man from the Christians made food for him, so he said to Umar; I would love that you and you companions come to me and honor me (and he was a man from the nobles of Shaam) so Umar said to him:
"We do not enter your churches because of the images inside them."
[Shaikh al-Albaani said: Reported by al-Bayhaqi with an authentic chain of narration as al-Haafidh said in al-Fath. ]
